Global Youth Engineering Climate Conference 2021

The Global Youth Engineering Climate Conference 2021 (GYECC21) online virtual event took place on 7th and 8th September 2021 with exhibits and facilities being available thereafter until 12-Nov-2021. Over 4,000 attendees for some 100 countries joined the event. Use #GYECC21 in social media posts. Access facilities via https://gyecc21.onbeehive.global/








The virtual event platform used is “Beehive” (https://liveunion.co.uk/beehive/).

A few observations on the Beehive platform:

  1. The animated “Eco-Park” orientation approach and entry to the various areas works well and is easy to use and navigate. Watch out for “Nessy”.
  2. The “Points” system encourages exploration of the exhibits and galleries as well as use of the collaborative aspects of the platform.
  3. When an attendee tries to set up a 1-1 meeting, there was no means I could see to message them to better arrange mutually convenient times, or discuss in advance the topic of the proposed conversation.
  4. When trying to suggest an alternative time for 1-1 meetings for someone who had previously suggested a meeting, the time slot selector briefly flas

360° Snapshots in Second Life 6.4.23.563579

linden-lab-360-snapshot Since 2016 a Second Life “Project Viewer” has been under development by Linden Lab that allows for the creation of 360° snapshots in Second Life virtual world scenes (see this earlier blog post). After a period of inactivity, a new version 6.4.23.563579 was released on September 3rd, 2021.

The 360° Project Viewer allows for the capture of 360° panorama (equirectangular) snapshots which can be saved to the users’ local computer and then viewed or shared via social media streams, uploaded to sites that support 360° images such as Flickr, or viewed in VR for example via the “360 Photos” app for Oculus Rift. The facility can be accessed via the Viewer menu “World” -> “360 Snapshot”. For convenience, a User Interface button can be added to the menu bar to provide access to the 360° Snapshot Tool, or a link off the standard 2D snapshot tool also opens the 360° tool.

Set a suitable viewer distance for what you want to capture, and I find it best to look round and ensure all content is concurrently visibke without refreshing as you look round. Try increasing the viewer cache size if it doesn’t.

Image Quality Choices

All 360° images are created as 4096×2048, 24-bit colour and 96dpi. The quality settings vary in the JPEG image quality saved setting, and hence the file size. All image quality levels looked crisp except for “Preview” which appears blurry.

The above 360° images can also be viewed in this Flickr Photostream.

Issues Remaining with Second Life 6.4.23.563579 Project Viewer

  1. The “Preview” quality settings appears blurry in all instances. Perhaps a refinement to the quality being created here to make it the minimum that would appear crisp would be useful.
  2. When using the “Maximum” quality image setting, a few times some objects in view, such as a sailboat, was only partially rendered. Dropping to the next level down “High” quality appeared to render fine.
  3. The 6 sides of the cube “skybox” that are created to form the image can show clear demarcation lines at the sides of the faces… especially when the sky light varies a lot between the directions. The sea level can also appear with a straight edge and corner where the sides of the cube meet. See example to right.

Second Life – New Account Sign Up Experience

This is feedback after trying for myself the recently changed new account sign up web experience after receiving comments from professional colleagues joining Second Life for the first time, and being surprised at unsuitability for their purposes for the starter avatar they were given without choice BEFORE they were logged in, were visible to others, and used the appearance and avatar selection facilities. An issue seems to be the lack now of a selection of a starter avatar closer to their purpose and preferences BEFORE entering in world, as used to be the case (see this blog post of the process in 2016).


There seems to be no mention you have to go to e-mail and check that for the verification mail that is there. The viewer just says could not log you in!

Initially I could not log into the viewer the password accepted at account creation time, so thought that the password I had used must be wrong. I had remembered it correctly, as I could log in to the web account page. BUT when I came to change the password on the web it kept complaining the password was not suitable. I had to add more special characters and complexity than the instructions of a suitable password indicated before it was accepted. When that was accepted on the web page it also worked in the viewer. So there is some mismatch between viewer checks and account creation checks in terms of password complexity allowed (as at 30-Aug-2021).


The new avatar arrives at a “Welcome Island” where a few orientation areas allow the new avatar to get used to the environment. A Guidebook” is displayed in the viewer to walk the new user through the initial essential things of movement and interaction between objects and other avatars. the Guidebook and tutorials can be recalled at any point via a button in the viewer, and the user can return to a version of the Welcome (Back) Island – not the original one so new users are protected from hassle).

The initially allocated avatar seems to be arbitrary. Though feedback from colleagues indicates a single choice for female (shopping girl!), male (orange shirted 70’s bloke) and Chris (for no Gender/Non-binary) seem to be the avatars appearing on the starter/welcome region. I understand avatar appearance and complete avatar selection can be altered in the viewer, but a lot of users may be unhappy with the initial allocation in terms of look, shape, skin colour, etc. My colleagues say they lao feel under pressure at this point as they are aware they are in a place where they are seen by others. Removing the avatar selection carousel may not suit everyone. Maybe show the initial avatar choices or a “select later in world” option at account creation time? Or fundamentally change the initial process to use a personal “changing room” space BEFORE joining any public space.

I could not see an area where Linden Lab sought feedback after I logged in with the new avatar.


Details After Some Use

As soon as I began to obtain some of the avatar items and complete avatars, I realised that all empty folders in the inventory were not (by default) displayed. That meant when it came to amending or making a new shape the “Body Parts” folder was not visible to place these items in and to encourage organised inventory for new users from the start. This can be changed by the user, but is not obvious to new users.

It is also the case that opening group and friends tools to participate in social events is quite deeply buried. Placing these choices on the right-click context menu for the avatar (as it was for many years until recently) would be helpful.

Re-Vue

This blog post is to support a short project to have University of Edinburgh Information Services (IS) folks get started with (or return to) Second Life as part of the handover of some of the work with the Virtual University of Edinburgh (Vue) from Austin Tate (avatar Ai Austin) who has acted as the Coordinator for Vue from 2007.


Vue is a virtual educational and research institute bringing together all those interested in the use of virtual worlds for teaching, research and outreach related to the University of Edinburgh.

Project Aim from IS

Stuart Nicol on 24-Aug-2021: “I was thinking about getting some people in my team more up to speed with Second Life/OpenSim. One way to do this would be to get a couple of folks to work on a practical experiment. I’d like to set up a virtual office in SL as we return to our physical office … by setting up something akin to the approach used in the Vue virtual graduations (a screen in the office showing SL and avatars of those working at home, and a video feed of the physical office being displayed in SL). I’ve identified a couple of people who are willing to help with this, and was wondering if you would be able to advise them on how to set this up? It would mean that they begin to get up to speed and we would be in a better place in relation to keeping some knowledge of the environment.”

Suggestions

I think its a good idea to start in Second Life to gain experience. They can install the official Linden Lab viewer, but (later) I would suggest though that your team use the Firestorm viewer rather than the official Linden Lab one. FS is the most widely used viewer in SL but also has the advantage that a version of that same viewer also can be used on both SL and for the open source OpenSim grids. http://firestormviewer.org. Both can co-exist anyway.

When you first enter Second Life there will be a welcome/tutorial area to help you get started. But here is some info and a short video…
https://community.secondlife.com/knowledgebase/english/second-life-quickstart-r373/

Have ONE of the users register in SL with a “Premium Account”? It can be done monthly ($12), but my suggestion is to do it as one annual payment as its quite a bit cheaper… $99
https://go.secondlife.com/premium

This will allow that user to have a 1024sq.m. plot on a LL region without further payment… such as one of the Linden Homes in various styles.. like the houseboat I have. I think this is a good way to get a simple start and it can easily be changed later to a different style or to a custom use mainland plot (you just abandon the plot you already may have first), or even a private island like we used to have.

The rest can use free accounts. I will suggest a group is set up to link these folks. The premium user will get L$1000 (about US$4) as a starter fund and L$300 a week to have some funds if needed to buy items. Some free items for avatars can be found at helping Haven Gateway in Second Life at its “Freebie Village” via this link… http://maps.secondlife.com/secondlife/Helping%20Haven%20Gateway/173/42/25

With that in place I can maybe join the folks in world and help them set up the office/base to support the group, rather than just the individual owner) and set up a media screen that should support the video stream inwards.

OpenSim can follow along if things work out… maybe by setting up an addon region in OSGrid to replicate what is set up in SL, but maybe starting with the OpenVCE collaboration region content as an initial setup.

Sample Video Live Streams

The aim is to link a real world space in IS via video into Second Life workspace and vice versa. We can explore a suitable format to use to play in world, but pretty much anything that will play in Google Chrome will work (as SL uses the Google Chromium Embedded Framework (CEF) library to play content on inworld media surfaces.)

E.g. for a YouTube Livestream – use the embed/<video>?autoplay=1 form:

Temporary Facilities for Meetings in Second Life

A number of Open Educational Resources (OERs) are available in Second Life to set up Vue facilities. See the blog posts Vue -> Openvue and Vue and OpenVCE OERs.

Skateboarding in Scotland in 1978 and 1979

The Tokyo 2020 Olympics (actually run in 2021 due to the COVID-19 epidemic) introduced Skateboarding Freestyle and Park Riding into the event list for the first time. It reminded me to go back over some of the early championships run in Scotland and at UK and European level back in 1978-1980.

I was Competitions Secretary for some of these events and Secretary for the Scottish Skateboard Association at the time as well as a skateboarder in the Edinburgh University Skateboard Club. We were fortunate to have excellent park/bowl riding facilities in Glasgow at Kelvingrove Park (see this short movie from the time) and in Livingstone, both of which had enlightened and enthusiastically supportive Recreations & Parks departments. A few of the competition programmes and competition regulations used at that time are reproduced here.

Open Educational Resources – Vue and OpenVCE

This is a blog post to support resources from the Virtual University of Edinburgh (Vue) and Open Virtual Collaboration Environment (OpenVCE) activities to make them available on http://open.ed.ac.uk. Contact – Stephanie Farley (Charlie). Downloads available are in http://vue.ed.ac.uk/resources/open.ed/

See https://open.ed.ac.uk/virtual-world-simulator-platform-resources/


Vue is a virtual educational and research institute bringing together all those interested in the use of virtual worlds for teaching, research and outreach related to the University of Edinburgh.

Even before Second Life began to be used across the University of Edinburgh in 2007, groups in Business Studies, Education and Artificial Intelligence/Informatics had been exploring virtual worlds platforms for a range of collaboration, educational and research project uses. Early Multi-User Dimensions (MUDs), platforms (now long gone) such as “There” and commercial virtual world simulators such as “Forterra” had been in use, and Second Life itself had been used even in its very earliest incarnation.

The following blog post indicates what Vue usage there has been of Virtual Worlds…
https://blog.inf.ed.ac.uk/atate/2018/04/27/virtual-worlds-technology-for-university-of-edinburgh/

The original Second Life Vue regions used from 2007 to 2019 are no longer maintained, but resources are available to use any available space in Second Life and a similar set of facilities are available on the OpenSimulator Platform and in some other experimental virtual worlds platforms…

Virtual Worlds Regions and Content

The Openvue “mini-continent” contains 12 256mx256m regions…

The lower right hand corner contains the “OpenVCE” (Open Virtual Collaboration Environment) region created by us and made available an an open educational resource that anyone can obtain and use in Second Life or OpenSim (see this blog post). It is also available as a selectable starter region on a range of OpenSim hosting platforms.

Open Educational Resources – Vue

Available via http://vue.ed.ac.uk/resources/open.ed/

  • OpenSim OAR (OpenSimulator Archive File) and terrain (.png and .f32 formats) for each region in the Vue “continent” as originally mounted on Second Life.
  • Extra OpenSim OARs and terrain files. Edinburgh is a variant of the Edinburgh Uplands region with “Edinburgh Castle” and “High Street” content that can stand alone. Sea-Vue is a simple region with only water and can be used for infill between other regions where useful.
  • Male and Female “Bots” avatars.
  • Second Life Marketplace – Ai Austin Store – resources to create temporary facilities on Second Life sandboxes or other areas where they are allowed to build.

Open Educational Resources – OpenVCE

OpenVCE content for Second Life is available via the Second Life Marketplace:

OpenVCE content for Opensim is available via http://vue.ed.ac.uk/resources/open.ed/

  • OpenSim OAR of all core elements and buildings.
  • OpenSim OAR of a pre-arranged collaboration region.
  • Presentation screen adjustments to scripts.

Vue Collaboration Facilities

Vue Regional Planning Authority (VRPA)

The rather grandly named “Vue Regional Planning Authority” (VRPA)* is a small group of people from across the University of Edinburgh who raised funds for the Second Life and OpenSim Vue regions and servers and were involved in the design and creation of the facilities. The group continues to be involved in explorations of other virtual world platforms in their own Schools, groups and across the University for the potential benefit of others. [vrpa@lists.ed.ac.uk] [Admin: https://mlist.is.ed.ac.uk/lists/admin/vrpa]

*name suggested by Hamish Macleod.

Making Fresh OSGrid Addon Regions

A new set of regions could be created with new region owner avatar(s) and content restored via save and load OAR (OpenSim Archive files) which are now archive on open.ed.

Temporary region names would be used, but once the new regions are established and running well, the original Vue addon regions on OSGrid can be closed down, and then the new regions can be renamed to their original counterparts.

Continuation of Second Life Capabilities

I-Room-2007-08-23-IX-2 I-Room-2007-08-23-IX-3-new

The University and Schools no longer own specific regions in Second Life, but a foothold could be achieved by having a small home/office setup. This could perhaps be most effectively done by having a user (normally free) become a Premium Member (approx. US$99 per annum) which gives a weekly stipend of around US$1.25 per week and allows a 1024sq.m. personal space with options for a range of prebuilt home styles (Linden Homes), e.g. such as this “Houseboat” style used by Ai Austin.

Making a Fresh Openvue Grid

Over time the databases and content for the OpenSim-based Openvue and the Vue regions added onto the openly accessible OSGrid have grown and an occasional tidy up can be be beneficial to ensure only truly accessible content and active avatar users are included and the data base size is reduced. As at July 2021 the Openvue MySQL data base when dumped to an SQL file as a backup is 18GB. There are 36 avatars included, quite a few of which are inactive.

A new OpenSim “ROBUST” grid can be set up with a new administrator and a single new region owned by the new administrator. This can become the welcome or landing region for the new grid. The grid and any regions can be renamed later. Further regions and active content can then be added via recreating the key content owning users (create user with previous UUID) and loading their inventories (via save and load IAR – Inventory Archive files) and then setting up the regions afresh and restoring their content (via save and load OAR). Once the new grid is established and running well, the original Openvue grid can be closed down.

Issues for the Future

To improve security, the University of Edinburgh may not permit non-central services staff to run or manage services and applications accessible outside of the University and may require use only by internal users or those with login access via VPN to ed.ac.uk. This could mean that OpenSim Hypergrid access to external users and potential external visitors to meetings or viewing content held on OpenSim (Openvue) would not be able to gain access.

OpenSim Openvue grid and OSGrid Vue regions make use of a free vivix voice license that was offered to educators, non-profits and small grids on a free basis. Vivox is now owned by Unity and they have announced that new free licenses will not be offered. Voice is an important facility cor Vue uses of virtual worlds. An alternative may have to be found in future. Dome people have experimented with self hosted open source “Freeswitch” servers for voice.

Notes on Security for OSGrid Regions Running in ed.ac.uk

To enable discussions about the risk of running OSGrid addon regions in inf.ed.ac,uk or ed.ac.uk the following notes might be helpful.

OSGrid is the main development, testing and community hub for and provides free avatar registration for users. It is a non-commercial grid that runs on community support and donations. It allows self hosted regions to be added in a simple way. OSGrid central servers and the core databases are hosted in the USA. OSGrid allows a simple way for anyone to host their own add on regions and manage that virtual world space. Users agree to the terms and conditions of usage centrally and their details are not managed at all locally by regions. For each region one port (typically port 9000 and upwards for more than one region) has to be accessible for TCP and UDP. Local regions can set a very wide range of policies for users to their own regions, e.g., to allow access to members of specific users or groups, prevent local building. etc, and even close the region completely when needed. The default policies have safe limits on what scripts can run and are set to prevent external interaction with the underlying operating system.

Nebula 75: a day of puppets at the University of Hull

Hosted by the University of Hull on 27th may 2021, there was a live screening, Q&A, discussion and live onstage filming re-creation of a key scene with the team behind the web series Nebula 75, which was created during the Corvid-19 lockdown of Spring/Summer 2020. The productions uses ‘Supermarionation’ puppetry techniques originally developed by Gerry Anderson and Sylvia Anderson as well as the ‘Superisolation’ techniques that the team developed themselves by necessity as the series was recorded in their London flat.

BIS Event – Ron Miller – Space Artist


Ron Miller gave a presentation at the British Interplanetary Society (BIS) online event on 19th May 2021 (web page). Ron Miller is an internationally acclaimed artist who is focussed on space themes. I have been a fan of his work since the 1990s when I got his book with William K. Hartmann entitled “Grand Tour – Traveller’s Guide to the Solar System” and later books.

“Long Distance Traveller – the Life and Work of Space Artist Ron Miller”

Replay of the event on the BIS YouTube Channel:

During the presentation and discussion Ron described some of his techniques and tools. Having started off with traditional painting techniques, he changed to digital art. He typically takes 3 to 4 days for each image. Much of teh work is done in Photoshop, but for some elements he composes into the scenes he uses a range of methods and tools. GHe uses TerraGen to create some landscapes as 3D models. He also uses 3D models of spacecraft, such as NASA models. He has 3D printed some parts to photograph and include in compositions. Recently for his own interest he went back to using traditional painting in acrylic for some images.

Shane Pickering – Supercar Cutaway Take Two

Shane Pickering, a graphic artist and private pilot in New Zealand, in the late 1990s worked on schematics and internal details for Supercar compatible with the TV shows and annuals. Details in this blog post (20-Jan-2016). We had a lot of exchanges about plausible internals for Supercar taking into account many references in the TV shows and (mostly) using plausible aerospace concepts with a bit of advanced technology known only to the research community of the time. Remember the late 1950s and early 1960s was the age of the hypersonic X-15 rocket plane, Harrier VTOL Jump Jets and the SR-71 Blackbird!

Now Shane is carrying on the work he started two decades ago by producing a technical “cutaway” based on the detailed schematics.

Shane’s Modifications to Supercar Model

Shane has modified the details of the Supercar model based on improved resources, and these largely coincide with similar improvements in accuracy compared to the puppet-scale studio model as incorporated by Mick Imrie in his “Take Two” Supercar 3D model as described in this blog post (23-Feb-2021).

  • Nosecone enlarged and intake fins straightened and skinnier (I haven’t reduced the width of the front intake as that is fairly major and would need some major “redrawing”.
  • Nosecone spike corrected for a closer match to Mick’s model – spike is straight not tapered as per my notes (Mick corrected me there).
  • White/silver upper panels lengthened and reshaped towards the front, front lights enlarged, more curvature added, rotated and moved forward.
  • All of the chrome trim changed to gold and dash trims either side of the Clear-Vu made the same length.
  • Windscreen rubber seal straightened over top of the Clear-Vu and more rounded running off to the side to connect to the front canopy frame.
  • Right-hand corner of the Clear-Vu rounded off a bit and the shape altered based on frame grabs.
  • Thin grey line added onto the top FlexiGlass to explain the “seam” – those little canopy supports (added to the rear frame) can be explained as part of the seal mechanism (this is sitting on a separate layer so it can be removed if you prefer).
  • Interior and rear seat inserts changed to similar dark grey; (I now know the rest of the interior incl. the bask seats are actually blue – I experimented with that and frankly it looked awful (what were they thinking)??? As it was in B/W, I guess no-one would notice. 🙂
  • For the sake of consistency and accuracy, I’ve reshaped the back seats and removed half the “buttons”, again based on frame grabs. I’ve curved the white front seat strips a little to give the illusion of them having more shaped padding rather than flat), again based on the frame grabs.
  • Not too sure about adding the exposed piping/tubing visible in some interior shots (between the front and back seats on the sides) – I can show that as part of the cutaway for a bit more interest (I can see they lifted a lot of that straight out of old fighter jets of the period). Ugh – hide it behind some panels.
  • Left front hull contour slightly “straightened” from the side intakes forward, but I haven’t altered it heading rearward. Instead, I’ve reshaped and flared out the lower part of the side intake where it connects to the hull. The lower step has been slightly altered but the upper step and heat extractor vanes are unchanged.
  • Stretched the line of the wings a little where they go into the hull to create the illusion they’re a little higher and thinned down the “hole” they slide into, also to make it look as they’re on the upper curvature of the hull and also a tighter fit; I haven’t repositioned the wings but just added a little more onto the rear of the wings.
  • Wing pods completely redrawn to more closely match Mick’s new model; they’re shorter with flattened ends and the spike is a closer match.
  • Four rear jets have been slightly reshaped (more curve on the top).
  • The left tail fin strake thickened a little near the rear cockpit frame to give it a more uniform shape than what I drew previously.
  • Second fuel filler added to right hand side and redrawn the left as domed rather than the octagonal shape I had earlier.
  • Trim across the top of the front seat back widened.
  • Now I haven’t touched the canopy/frame (for good reason); Mick and I concluded that was quite a bit off in the original but would require a major redraw at my end (i.e. its longer and shorter towards the rear frame).

Overall, about 70% of this rendering has been altered compared to the original, and much more carefully drawn. Overall, I think it’s a big improvement and a more accurate representation over the original.

Earth Day- Vangelis

Earth Day – 22nd April 2021 – Space Rocks – Vangelis

I have been a fan of Vangelis since hearing his track “Alpha” (from Albedo 0.39) on the collection of music loved by Carl Segan when he was on BBC Radio’s “Desert Island Discs” and used by him on his TV Series “Cosmos”. Vangelis has been a soundtrack to future sounds in films like Blade Runner, and in composing pieces for space missions like NASA’s Mars Odyssey (Mythodea) and ESA’s Rosetta spacecraft and Philae lander.

Trying to make sense of Black Rock Laboratory

The fictional base in the Nevada desert for the team in Gerry Anderson’s Supercar TV series is called Black Rock Laboratory. For 3D modellers it is a nightmare as many of the sets used in the TV series are separate filmed elements and do not sit well together or fit sensibly into the external envelope for the lab. The lab exterior only appeared as a drawing in series one.

BRL-Sketch

This was replaced by a miniature model built by Derek Meddings in series two. The series two model added an extra concrete reinforced blockhouse on one end, and it might be that Derek did this to house the control room which protrudes beyond the roll up garage door as seen from the inside of the hanger.


Colourised-Black-Rock-Lab


Mick Imrie built a 3D model of the core Supercar hanger part of the lab interior to try to make sense of this… and Austin Tate built a simple exterior model to fit this in. The lab is arranged in 5 segments: two contain living accommodation, then two over the Supercar hanger floor area with roof door overhead, and then a final segment over the control room. There is a block of smaller rooms along the front of the lab and a separate smaller building with the radar dish on top.

Images of the Interior Looking Towards the Control Room

Images of the Control Room Position and Roll Up Garage Doors

Some TV images do allow (with a bit of imagination) for an interpretation that the “internal” roll up garage door leads to an area that is still within the lab space and is not directly to the outside. And that the outside door is different to the inside one…

Unfortunately external plants show in the image from the outside viewpoint, as confirmed by a wider shot in the Runaway Train episode.

Assumptions for Modelling of Black Rock Laboratory

  1. The Supercar hanger area is very well shown in the TV series and if at all possible its visual appearance and layout ought to be preserved.
  2. That means that the Control Room is within the floorplan of the main laboratory rather than being housed in the blockhouse added for season two.
  3. That also necessitates a double garage door arrangement.
  4. The door to Beaker’s Laboratory appears to lead directly outside unless an extended lab space of approx. 1.7m single storey area is added behind the lab.

Trying to Make Sense of This

The sets used for filming were often separate or rolled into position depending on the camera angle. So, of course there are a number of problems with the Black Rock Lab layout as used in our models to date…

  1. From an inside view of the lab, the roll up slatted “garage” doors are flush with the front of the control room, whereas on the exterior they are situated on the end wall.
  2. If the control room is set where shown in the TV stills, then the interior part of it cannot sit back into the blockhouse, which would have made some sense as a protected location.
  3. Dr. Beaker’s lab door is alongside the high voltage equipment area, but that would lead directly outside the lab. The “Laboratory” door would have to lead to a corridor width passage behind it and then access to the right to a room alongside the control room for this to make sense.
  4. Position of the elevator must be in corner somewhere to the left of the AVGAS hose door, but it does not show in TV stills showing the control room wall. Perhaps it could be there but hidden by the “internal” roll up garage door when that was closed.
  5. The elevator shown in “Tracking of Masterspy” and “Talisman of Sargon” shows an indicator for 4 levels whereas the lab is a 2 storey building over a basement area. Masterspy also appears to come DOWN from Level 3 which he refers to as the “gallery” when he steals into the Lab.
  6. After the “Rescue” episode Jimmy Gibson is shown in a bedroom that looks out through the double doors under the gallery to the Supercar hanger floor area, whereas in other episodes a corridor is behind those double doors.

Revised Black Rock Laboratory Plan

Firstly lets change our current 3D model to more closely resemble tge season two model by repositioning the blockhouse more centrally on the end wall and making its floor plan square, and widen the block of bedrooms or offices at the front of the lab a little to allow space for a corridor. And show a possible area where the basement sits (in red). Some adjustment to the radar/communications block upper structure and the upper windows in our original 3D model building also needs to be made.


The main externally visible change is the addition of approx. 1.7m of extra space for Dr. Beaker’s Laboratory at the back of the building.

Seeking to Explain the Control Room Placement and “Garage” Roll Up Doors

We have to accept there are multiple (non-exclusive) possibilities here:

  1. The TV stills show the control room front flush with an internal garage door, and fairly close to the nose of Supercar in the hanger. This would imply that there are two sets of garage roll up doors separated by one unit of the 5 unit laboratory. That would be enough space to park a pickup truck, and tyre marks are shown in outside views going into that space.
  2. The blockhouse addition was probably meant (by Derek Meddings in season two) to house the control room interior, so the control room is really set back one whole lab unit. There is then just a single garage door.
  3. The blockhouse should not be there at all and was a continuity mistake!
  4. The blockhouse was a later addition to house Dr. Beaker Experiments and to provide a playroom for Mitch!

I am going for the moment with (1) and (4)!

Supercar Annuals – More on the Position of the Blockhouse

In the Supercar Annuals, EVERY image of Black Rock Lab that shows the blockhouse has it positioned to the extreme right hand edge of the end wall, not in the middle as in the Derek Medding’s studio model. But the images also add an extra “segment” to the lab and also extra bedrooms along the block of rooms at the front.

Interesting, MOST interesting… if it was in that position it could be that it directly is alongside Dr. Beaker’s lab in the back corner of BRL.. and there could be the experiment observation hatchway through to it from the lab end wall? But I am sticking with the Derek Medding’s model position for the blockhouse as centred on the end wall.

Seeking to Explain the Position of Dr. Beaker’s Laboratory

This is a tricky one. The door as it sits alongside the High Voltage zone would appear to lead directly outside. There are two possibilities perhaps:

  1. The door leads to an external room. Unfortunately the series two model seen from the back does not show this clearly, though many of the images of the back side of Black Rock laboratory are in deep shadow!.
  2. The door is misplaced and actually stands inwards a little (corridor width) and then the Laboratory itself opens to the right off that entry space and is placed alongside the control room.

After consulting with Mick Imrie, I am going with (1)!

There is a TV screen shot of the laboratory door partially open where it seems that there is a narrow corridor snd wall immediately behind the door, rather than the main laboratory space opening out immediately behind that.

Seeking to Explain the Room behind the Double Doors under the Gallery

The double doors might open onto a corridor that runs to the side rooms and in some way to the kitchen/lounge areas. A further set of double doors aligned with the hanger bay ones would allow Jimmy after his rescue to see through when both sets are opened.

There is likely a corridor behind the double sliding doors across which another set of double doors gives access to a room that may be a guest bedroom and/or infirmary.

Jimmy being in the “bedroom” that looks out to the hanger floor in the first Rescue episode might be explained by that being an infirmary or guest bedroom and not Jimmy’s allocated bedroom after he joins the team! We see a TV monitor in the room on which Mike shows Jimmy Supercar in the nearby hanger before opening the double doors to show him the actual craft.

The rooms alongside the lab in the single storey may all be bedrooms as the lights all come on in all four rooms one at a time when the team is disturbed one night (episode 70-B-Lo). Popkiss’s room light is already on first, so his bedroom is at the left of the block of bedrooms.

Seeking to Explain the Elevator Levels

Is this a plausible explanation of the 4 levels shown on the elevator indicators?

  • Level 1 – basement (partial floorspace of lab only) where safe is. Assume its an area where AVGAS tank is under the AVGAS door, boiler room, mechanical workshop and storage.
  • Level 2 – hanger floor level
  • Level 3 – mezzanine level within garage area to access gantry
  • Level 4 – engineering position to locate lift a metre or two above highest normal level for elevator repairs

In the episode “Tracking of Masterspy” Masterspy (dastardly man that he is, and due to careless BRL team security) had snuck in through the outer garage doors and had already taken the lift to the “gantry” level (level 3) at that end of the lab (Masterspy refers to it as the “gallery”) to spy on the team from behind the (closed at the time) inner garage roll up doors to wait for the plans in the briefcase to be brought over by Jimmy before he re-enters the elevator to descend to the hanger floor “ground” level (level 2) as Jimmy approaches it!

Seeking to Explain the Position and Use of the AVGAS “Door”

The red AVGAS panel in the corner of the laboratory hanger floor has on it the SAVGAS fuelling hose and valves. The panel looks like a door, but with no handle. It does not match up with any external door in the lab, so it must just be a panel attached to the wall.

Seeking to Explain the Upper Storey Windows Slats

The external appearance of the window slats appear narrower than those on interior hanger bay views.

To reconcile these, the outside appearance could be designed to offer sun protection to the interior by using a outer beam that has a tapered shape which is wider on the outside and is narrower at the inner side to leave an opening there between beams that is wide enough to match the larger internal window glass panel.

Speculation on the “Garage” Area

Assuming that the lab has two roll up doors, and inner one and the external one, we can speculate on what is in that space… especially as TV episode camera angles don’t show its upper parts.

  • The space between the roll up doors provides enough space to garage a pickup truck. This is necessary as we don’t see the team’s truck parked outside in any TV episode.
  • The clearance available allows Supercar to be pushed out on roller skates with wings retracted, though Supercar’s wings are also removable to make it narrower for such manoeuvres if necessary.
  • The elevator shaft is positioned just inside the inner door. Hence the reason it is not seen in camera angles from the Supercar hanger floor.
  • There is likely a heavy lifting hoist and pulley mounted on a track on the ceiling of the garage area. This is used to load or unload heavy equipment from the pickup truck.
  • There is likely a floor lift that can lower or lift large items to or from the basement.
  • There is a garage gantry that can bridge between the elevator level 3 position and a doorway that leads to storerooms that sit above the control room and adjacent areas. This gantry is often not visible in scenes that show the garage area as it retracts telescopically and hinges up to fit against the elevator shaft when not in use… allowing full headroom clearance out through the garage when necessary. Note that Masterspy refers to this garage gantry as the “gallery” when he sneaks into the lab via the garage and elevator.

Speculation on the Tanks and Pipework at Back of Lab

At the back of the season two model there is a storage tank spaced well away from the main body of the lab, connected by pipework in a girder arrangement to the lab at the level of the building eaves. This could be AVGAS fuel, but it comes in high up, rather than near the inner lab door that has the AVGAS hose. Heating fuel would likely come in at a lower level or feed a boiler in the basement. Could this tank and pipework be related to air conditioning and/or fire protection?

Speculation on the Basement

The basement is referred to as “downstairs” from the Supercar hanger level and there is a safe down there. Some ideas for that level besides the safe could include an AVGAS storage tank under the AVGAS hose door, boiler room, mechanical workshop with heavy machinery tools and storage.

Speculation on the Pickup Truck


The truck is probably meant to look like a 1960 US vehicle. Mick Imrie thought that the small model shown on an exterior shot of Black Rock lab may be a Land Rover.

For colour, Ford Pickup truck colours from around 1960, especially early 1960s pastel colours, may be appropriate as its MEANT to be a US (Nevada) pickup. Land Rovers tend to be sludgy colours and often blue or green.

Maybe something like the Ford Tidewater Aqua (Ford 1960), Ford Waterfall Blue (1956) or Land Rover Marine Blue (1958-1971) could be the colour.

Speculation on the “Communications Block”

The separate building with the radar on the roof probably houses communications and computer equipment related to the radar, radio, telemetry and high bandwidth Clear-Vu links. Computers would be old style 1960s mainframes and tape drives. Power generation units for the whole laboratory and cooling units would also be needed for such equipment. A storage tank is located under the colonnade at the side of the building, which may house fuel for power generators.

Some Experiments with the 3D Black Rock Lab Model in OpenSim

The following images show Interior Rollup Garage Door closed and Interior Rollup Garage Door open with Elevator Position and Gantry in its retracted and folded up position and when unfolded and telescopically extended…


Following images show the area of the basement (terrain removed) and Dr. Beaker’s Lab Door access to his Laboratory which partially occupies the space next to the Control Room and a short extension outside (approx 1.7m extra depth) the main hanger wall line (with windows similar to the front block rooms)…


The Lab exterior therefore might look something like this (note the upper windows need better modelling to be similar to the Season two model)…

Mick Imrie – Supercar Take Two

Mick Imrie created a detailed Supercar 3D model in Cinema4D back in 1998-1999 and this has been used as the basis for many ports to other 3D modelling tools, game platforms, flight and space simulators and virtual worlds platforms since then. See http://www.aiai.ed.ac.uk/~bat/GA/supercar-3d.html.

Mick has now begun the creation of a new Supercar model taking on board experience gained. As previously, the reference point is the puppet-scale studio model. [There also was a mid-sized model and a smaller “flight” model details of which differed from the puppet-scale model.]

Mick is posting about the new model on the EagleTransporter British SciFi web site.

Fan Produced Model

Supercar was created by A.P. Film Studios in association with ITC (now ITC Studios). Supercar 3D Model by Mick Imrie with technical assistance from Austin Tate. Original Supercar designed by Reg Hill of A.P. Films. This is fan produced material to promote the shows of Gerry Anderson and provided for your enjoyment, and should not be used for any commercial purpose. Mick aims to make the Supercar models available to others.

Model Improvements

The new model accounts for some of the following inputs:

  1. Availability of higher quality visual reference material published over the years and higher definition TV screen captures from the TV series. Mick has been able to use these to provide corelated reference images to better inform the modelling shapes.
  2. The main hull shape has been refined using the detailed screen captures and normalising them. This led to the shape changing in ways consistent with Phil Rae’s 1990 revision of his Supercar blueprints. Wing position, nose shape and front light pod size and position also altered. Retro jet length was shortened.[Phil Rae produced a Supercar blueprint for a centrespread in Fanderson’s SIG no. 3 in Autumn 1981 and revised it in 1983 for a set of A3 Gerry Anderson vehicle blueprints. In a personal communication to Austin Tate on 18th August 1990 he offered further revisions as an amalgamation of the three studio models (Puppet scale, Bill James’s 3ft. version and the smaller “flight” model.
  3. Improved accuracy of the wing slot on the fuselage.
  4. Improved modelling shape of the side cooling vanes and the red fairings above and below them which slope rather than sit horizontally.
  5. Improved understanding of the colour and shininess of some parts and trim on the Supercar from improved colour reference material. E.g. the puppet-scale model hull piping is pale brass rather than chrome.
  6. Improvements to the texturing of the model to allow for simpler use on other platforms.
  7. Detailed research by Mick to identify original parts and instruments used in the construction of the puppet-scale model. He is documenting this material on a new web site to help other modellers. See ‘deconGA’ (deconstructing Gerry Anderson).
  8. Improvements to the Supercar dashboard using screen grabs of the human hand scale dashboard. However, this dashboard often had replacement instruments and switches to accommodate the story lines and cannot be reconciled to a single consistent model.
  9. Design to allow for a simpler texture based dashboard, as well as a detailed 3D modelled version to support different delivery platforms.
  10. Significant reductions in polygon count for the hull, fuselage piping and other complex curved elements of the design.
  11. Use of curve based modelling (NURBs) where useful but ability to export as polygons for those platforms needing this.
  12. Canopy structure, size of holes in rear support improved and added small block on rear support to support the canopy top.
  13. Cockpit interior details for the interior sides, front bench seat, rear seats and pipework in the rear corners was made using better reference images.
  14. Compatibility with Supercar Schematics Details (PDF) where feasible.
  15. An “add-on pack” for accessories such as Clear-Vu mounted gun and fairing, magnetic grabs, nose drill attachment, canopy mounted searchlight, etc. Possibly also in including the lab blast shield, Dr. Beaker’s lab console and remote console.

Canopy Structure

Mick has put quite a bit of work into getting the canopy structure to better reflect the Supercar puppet-scale studio model. This includes adding the small canopy top piece support block on the rear framework, and making the holes in that part more accurate.

Cockpit Interior

Details of the cockpit interior are to be improved. The front bench seat piping, trim on the top of the back (based on “Hidem Banding”) and the seat base shaping and upholstery buttons are all to be improved.

Dashboard Details and Instruments

Mick found that many of the instruments used appear to come from the cockpit of the Gloster Meteor NF12.

My own notes on the dash and the instruments that appear is in this diagram.

Model Complexity

The new Supercar model is designed to be less complex than the previous 1998/1999 version which had a high polygon complexity (measured in vertices and triangles). The 1998/1999 model complexity was approximately (see this blog post for initial mesh upload experiments):

Triangles: 135,000-165,000

The new 2021 model has complexity approximately:

Triangles: TBD

Supercar Colours and Fonts

Mick Imrie made these notes back in 1999/2000 for the original 3D model…
http://www.aiai.ed.ac.uk/~bat/GA/SC-MODEL/IMRIE/MODEL/information.txt

    The font used for the Cinema 4D Supercar model was a TrueType font supplied with Corel Draw called SWISS911 XCm BT (free download). This was selected primarily on the basis of the ‘S’ shape. The logo is obviously all in capitals, the ‘S’ is 118 point size and the rest of the characters are 78 point.

    On the subject of colours, Austin and I spent some time trying to get the colours as good as we could given the vagaries of colour photography. What we came up with are as follows (all given as RGB values):

         Red bodywork:           255,0,0
         Light blue:             204,255,255
         Yellow:                 255,255,0
         Off-white bodywork:     254,250,230
    

Piping noted as likely a light brass colour on 3-Mar-2021. Perhaps “Gold Tone” Brass such as in this example [Local Copy of Image][RGB: 236,236,186].

Shane Pickering has more closely studied the font, letter shape (the “A” is rounded at the top) and shape of the lines at each side of the logo. The following logo is traced off a close-up of the studio model and normalised (original and Photoshop .psd version here).

Shane Pickering has also been studying the Supercar colours as part of his work on a detailed technical cutaway for Supercar. He has been assisted by a friend who is a classic car restorer. For the “off-white bodywork” colour using reference colour photos, such as the Suter’s Store Windows Display, he has suggested we “aim for a middle range light grey with perhaps a little brown in it”. A light grey with a hint of beige perhaps from the “Palomino” colour range used on General Motors’ Cadillacs and Pontiacs in the late 1950s and early 1960s.

I am exploring the 1960 General Motors Pontiac Palomino Beige with RGB: 236,236,230 which seems to look a bit like the colour in some of the scans of the Supercar LP cover image. I also tried RGB: 230,230,224 and RGB: 224,224,218 but maybe they are a bit too dark.

NASA Perseverance Mars Rover Landing

On 18th February 2021 the NASA Perseverance Mars Rover landed on Mars..

This was my setup for watching the mission with NASA TV Live and a real time simulation of the landing in NASA Eyes…

Along with participation in the British Interplanetary Society Mars Rover Landing Party in Zoom…

The Rover is the size of a small car…

Real Time Landing Simulation


First Image from Mars

Congratulations NASA and JPL

Importing Mesh to Second Life and OpenSim

This is a page of resources related to creating mesh models suitable for upload and use in Second Life and OpenSim.

Beq Janus Advice

Beq Janus, who improved the mesh uploader now in use in Second Life/OpenSim viewers, and hence understands the limits, offered this advice…

  • Mesh limits more correctly should be interpreted as applying to each mesh element, not the whole model.
  • It is each sub-mesh in a model that has a 64K vertex limit because as you might surmise there is a 16bit index involved.
  • Every material is split into a separate mesh because it will enter the renderer differently depending on its nature (alpha blended, bump mapped, etc).
  • If a hard-surface model approaches the limits you need to go back to the drawing board… it is not a good model for any gaming platform.
  • Nurb models are certainly not allowed.
  • The models need to be triangulated too, not quads, you can let the uploader do that for you but frankly I would never leave a job like that to be done automatically.
  • You will need to take your curve based models and convert them to mesh. Again, even if you did have the option to convert on import the viewer would have to decide on the sampling frequency and you’d lose control of how it appears.

Collected Hints

  1. Any 3D modelling software will work, as long as it can output models in COLLADA (.dae) format. Note: Second Life uses COLLADA 1.4.1. (see Second Life Wiki – Mesh Background Information
  2. A “model” can have many separate “mesh” parts in it.
  3. The maximum mesh asset size after compression is 8MB, roughly equivalent to a 256MB raw COLLADA file. An entire region can support up to 128MB of distinct mesh assets after compression, not including attachments.
  4. A single convex hull is limited to 256 triangles.
  5. Maximum number of vertices is limited to 65,536.
  6. Scale limit is set to 64 meters.
  7. Take care to create low polygon meshes (as few verts as possible).
  8. Use no more than 8 face textures (8 materials assignments) on any mesh. These will import as “faces” in Second Life/OpenSim, which can be individually textured. You need to create a UV mapping for your model and its mesh parts which defines what part of the texture will go on which polygons of each mesh.
  9. Avoid intersecting faces (unless intersections are intended).
  10. Avoid duplicate vertices (unless you want to use the split modifier).
  11. Avoid creating more than 21844 tris per texture face.
  12. Avoid creating extremely small polygons (< 0.1 cm edge length).
  13. Make sure the objects, materials, submaterials and textures in the meshes do not contain any spaces. (so not “Box 001” which will give the “Error: element is invalid”, but “Box001” or “Box_001”).
  14. You can use any of the modelling tools while working on your model, but in the final form it should be saved before export as an Editable Poly.
  15. Before you export your mesh, make sure that it doesn’t have any stray vertices or overlapping edges. These will either cause unexpected visual results in Second Life or worse, the mesh will fail to upload entirely.
  16. For all meshes, make sure that the “Up Axis” is set to “Z-up”. If the axis isn’t set to Z-up, the mesh axis will be flipped on its side and/or rotated in Second Life/OpenSim.
  17. Advice on Levels of Detail (LOD)… note the need for the bounding box to be identical in all models, and all LODs to have same number of textures. See http://wiki.secondlife.com/wiki/Mesh_and_LOD.
  18. Textures can be provided for the usual diffuse image, a normal map (Bumpiness) and for specularity (shininess). PNG and TGA formats are allowed. PNG is to be preferred. Stick to x/y dimensions that are a power of 2 as on import textures are reduced to the nearest power of 2.
