I'm wondering if it is possible to access any of the elevation data that
pov-ray creates when parsing a height_field. When I say elevation data I
simply mean all the y components of the triangles that pov-ray produces from
a heightfield. This would be useful for placing objects on heightfiels, for
example a grass macro that placed a blade of grass at the same height as the
triangles on a heightfield.

Nothing that will "in" POV-Ray as of version 3.1g, although MegaPoV does
have a 'hf_height_at' and 'trace' and version 3.5 will have the trace at
least. Both ways make it possible to retrieve a point (vector) on the
surface.
I have a feeling you wouldn't get exactly perfect positions but close enough
perhaps.

Thanks this looks a lot like what I was looking for, although not as
flexible as it could be I think it could be used.

I'm working on a new version of my grass macro that can use the trace function
to place grass on any object. It works quite well.
