No, it doesn't do an array, it writes objects with colours directly.

Got it and exploring now. Thank you.

Getting the height in-between the pixels requires some math.

True. However, you would have to do interpolation for intermediate values. And
finding the surface normal will be a bit more difficult, if required.

This sounds like it has potential to do many things, thanks for sharing it.

I don't know how useful it is to others, especially since I had the
impression it did just a fraction of what TGAMosaic did. If there's any
need for it I can make some changes so it'll work better for other
people. I live on feedback ;)

Margus and Warp, that's why I said it would be a heavier solution :)

Get the superpatch or megapov versions of povray and use the trace
function.
