I see at http://www.povray.org/documentation/view/3.6.1/63/ that, for example, a trace should be a "sphere sweep", and that would take digging into Jmol and pulling out the control points, not just a finished trace. Isosurfaces are just sets of triangles. The order that vertices are listed determines which side is which for lighting purposes. We do expose these triangles via a public interface now, so it's entirely conceivable that we could "deliver" the essential information to something like POV-Ray in the format described by http://www.povray.org/documentation/view/3.6.1/67/. Actually, now that I see http://www.povray.org/documentation/view/3.6.1/68/, this is much more the Jmol model and is what one should use. Jmol has everything listed there -- a set of normals, a set of vertices, a set of faces -- all of it. In fact, the final bit there, about texture_lists, is what we would implement. The statement there: "By using the texture_list it is possible to specify a texture per triangle or even per vertex in the mesh. In the latter case the three textures per triangle will be interpolated. " is precisely what Jmol does.
To really pay off, I think we would want to do exports to POV-Ray that are not exact duplicates of what Jmol can do. Instead, we should use this as an opportunity to, for example, turn bonds into conic segments rather than straight cylinders. Same goes for cartoons. The goal should not be to reproduce what Jmol does but rather produce what Jmol cannot. I've been thinking that if someone wanted to do some work with POV-Ray and Jmol it would be a great contribution.
