Have you looked at OpenGL's feedback feature? It lets you capture
OpenGL geometry after it's been transformed to screen space, before
rasterization.
Wow, I wish I had known about that earlier. That's a great idea, in
fact it was super easy to rig something up to capture the whole buffer.
Any suggestions as to how to easily build a parser for the binary string
returned in the buffer, that is structured according to the grammar at:
http://www.opengl.org/documentation/specs/man_pages/hardcopy/GL/html/gl/feedbackbuffer.html
(preferable in windows, but *nix would be fine just to see how it works)?
You don't really need a parser. I think that a switch statement with
some loops (over the polygon vertices) would suffice.
