[Gnu3dkit-dev] Optimization suggestion

[Matt Brandt]

I'm going off the source to the 0.3.1r2 version or the G3DKit so maybe 
this is already in the new stuff. What I'm thinking is some way to have 
multiple representations of  a scene that automatically switch 
depending on the distance to the camera. This would be most useful for 
games and programs that need full speed rendering. It could be done as 
a subclass of G3DScene (maybe G3DMultiScene or something similar) or it 
could just be built into G3DScene itself.

In a typical application there might be one representation that is just 
a pre-rendered texture on a surface or a sphere and another that has 3D 
details. The details could be nested G3DScenes that switch from 
pre-rendered representations to full 3D when the camera gets within 
their detail sphere.

There shouldn't be any limit on the complexity of each representation, 
but I'm not sure I see a need for more than two levels of detail per 
scene.

What do you guys think?
