Sounds interesting, do you have it on your site?
What I'm actually looking for is something that generates "raw" data: the
number of horizontal and vertical points and an array of rgb-values.

I haven't tried TGAMosaic (yet); doesn't that do the trick?
Otherwise you can get the utility at my page
(http://www.xs4all.nl/~remcodek/pov.html). Look for ImagInc. It only
supports BMPs right now, but it'll be easy to put in other formats (as I
did with Bumper). The INC-file it spits out has 3 2-dimensional arrays,
for the R-, G-, and B-component of each pixel. You can change the
resolution (use low ones for testing). The melting rings and tentacle
thingies were made with this.

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.
