Re: NSOpenGL RenderKit

Hi,

I cc'ed the 3DKit discussion list, because I think this might be 
interesting...

Does such a renderer exist?

This is a very interesting issue. The GNU 3DKit was developed as a 
OpenGL based 3D framework only, although the idea to write it came from 
NeXT's 3DKit. Now my research interests have shifted a little and I am 
less interested in pure OpenGL based stuff. Up until recently I did not 
think of making the GNU 3DKit more generic, though. But then I started 
thinking about how the next gen 3DKit could be used to render a scene 
using different techniques (I am particularly interested in ray 
tracing, but other scanline based techniques would be interesting as 
well). My idea was to manage a scene in a scene database which could 
then be rendered by different renderers. Of course this needs much more 
thinking, but I now believe that it is worth it. This has the drawback, 
that a running version of it will be even more delayed though.

Is this really worth the effort, is anyone else interested in using 
such functionality?
