Just been watching a bit of the snooker between Trump and Higgins. Hazel Irvine and co. were discussing the amount of spin being put on the cue ball by using a cue ball with spots. She asked Steve Davis (I think) why couldn’t they play tournaments with a spotted cue ball. He said they do in some pool competitions, but the governing body for snooker has said “no”.
Anyway, so I thought of a possible solution, could the spots on the ball be invisible to the naked eye, but detectable by the TV cameras? Perhaps there could be infra-red reflective (or absorbent) spots on the cue ball, and the TV cameras could pick them up.
