Well, I think Marcus will have some thoughts on that. VTK now has GPU-rendered volume rendering. He's also been thinking for a while about better scaling rendering, which I think would be delivered in an Avogadro 2.0 effort once we get 1.1/1.2 out the door this summer and fall. > So far I've been using my own custom tool, an interactive direct volume > renderer that supports large-scale ball and stick vis.

Well, there is already a GLSL extension when available, and much can be done with this -- personally, I've been concentrating on building/editing tools so a Beyond that, you'd probably need to start on a new Painter class. We've tried to isolate real rendering calls into this class, so the Pov-Ray or other export methods use custom Painters. -Geoff ------------------------------------------------------------------------------ AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on "Lean Startup Secrets Revealed."
