Re: [isugamedev-devel] Glut Questions

[Kevin M. <ke...@vr...>]

I think the simpleGlut example on the isugamedev CVS sets up your viewing
for 3D...  all you would need to do is add in your geometry rendering at
the appropriate "TODO" point.  I think the function is called "Draw" or
"OnRender" something like that...

For the bike model, I would write a geometry loader, but you should be
able to approximate some stuf by coding the opengl by hand.  for geometry
model formats I'd use .obj, .ase, or .vrml.  I think 3d studio will export
all of them (need a plugin for .obj)
