Is there a macro for POV or patch that will place an object into a pov scene
according to an included bitmap?

Bascially an array of objects depending on the value at a pixel.  I seem to
remember this in polyray, but cannot locate it in povray or web searches.

Thanks,  Shaw

You should try megapov with it's eval_pattern/eval_pigment function:

BTW, this is somehow the wrong group for such questions, better ask things
in povray.newusers or povray.advanced-users

The excellent "vegetate.inc" might do it too.  Sorry, I don't have the url
handy :(
