[Gnu3dkit-dev] G3DBezier follow-up

[Brent Gulanowski]

Another question that I hope isn't idiotic, but how does one make use 
of a G3DBezier object? I mean, how could one draw one? Will we create 
some more G3DGeometryExtensions that will allow us to produce 
tesselated/submissible versions of the bezier, plane, sphere, line and 
other such mathematical objects in some form suitable for OpenGL? 
Actually, extensions alone might not be enough -- although I guess we 
could have something which returns a vertex array simplification.

Since OpenGL has support for NURBS (through GLU), would that route be 
worth considering? Or would we want to provide our own code? I'm making 
the hopefully not absurd assumption that we are hoping to draw Bezier 
and related curves. But perhaps the intention is to leave this up to 
individual users.

If (when) I manage to produce a dynamic procedural LOD mesh generation 
class (hey, I can always use the code in that article I quoted earlier 
-- the author posted C++ code for free, so I might just port it), maybe 
there will be some overlap in functionality.

This brings up a general question. I know of quite a few Open Source 
projects, most under the LGPL, which already have massive amounts of 
functionality in them, albeit mostly in C++ (Quesa, Crystal Space, 
Celestia, IScape -- a cool terrain renderer, Genesis3D, PanardVision, 
Gizmo3D). What is the attitude towards scavenging whatever we can find 
and Obj-C-ifying it for use in G3DKit?
