The OpenGL-patch did supporte most objects, some prymitives nativly in
example cone, cylinder, sphere, box, some - like CSG results - by
tesselation. I dont know how about the isosurface.

IMHO, it could be interesting idea to write a plu.. to write a patch that
will allow to convert any object into mesh (and smooth mesh) and
- - use mesh in OpenGL preview
- - use mesh in rendering of very complicated surfaces in complicated scenes
(reflections, radiosity, and so on)
- - save/load mesh  - cach it to disk
- - write it to disk (finally Pov-RAY to mesh-based-programs export :)

The macro mentioned to tesselate arbitrary isosurface perhaps could be
usefull for isosurfaces/CSG, and creating meshes for prymitives should be
easy.

For textures - they could be either normaly used, or pre-calculated to
images, one image per triangle even, with resolution based on size of given
triangle and general LOD (level of details settings).

BTW. is posting PGP signed messages a good idea on news.povray, or is it
rather not wellcomed?
