I have to say that for my part I at least partly agree with Mark. POV
already decomposes at least some objects into triangles (bicubic
patches and heightfields) It would be nice if it were possible to
decompose every object into triangles to within specified tolerances
for the simple reason that implementing things like displacement
mapping, OpenGL preview, and export to certain other formats (e.g.
3DS) would then be possible. On the other hand, I'm not of the
opinion that POV should be made to ALWAYS use triangles. For example,
it seems unlikely that you could render a sphere-of-triangles as
quickly as you can currently render the mathematical sphere.
And then there's the notion that we should just listen to whatever
Mark has to say just because he's the one saying it. He is the man
responsible for the MTV raytracer, oh so long ago (has it really
been over ten years?) and he currently works for Pixar, so he probably
knows what he's talking about.
