Thank you for the rotating colour-solid videos in wikipedia. They have been a great help to me (and I'm sure many others) in understanding colour. But I have come to realise that when a colour solid's whole reason for existence is to approximate perceptual uniformity, e.g. CIELuv and CIELab, then it is important to show the solid with the same scaling in all it's axes, except for any foreshortening due to the viewing angle of course. Your videos appear to exaggerate the vertical (lightness) dimension by a factor of about 4. It would be great if you could correct this. The viewing angle might then need to be lowered accordingly, so that we still get a reasonable view of the dark purple region.

Could you perhaps add Cabinet Projection (i.e. Cavalier Projection with scaling of depth by 50%) and Engineering (42°/7°) Projection to Projections/graphical_projection_comparison?

I'm using the diagrams from Wikimedia Commons in w3c/csswg-drafts#944.

Hi Mike. Great work, and sorry to be a pain. I don't use Windows and I cannot get POV-Ray installed on Mac. Is there an alternative Mac app I could use?

thx
