   OpenGL 3 and the Utility Library
  Will the glu routines still work with OpenGL 3? In particular I'm concerned about the tesselation routines like gluTessBeginCounter, etc. I'm guessing that in general some glu routines will be OK and others won't. Is there any info on this anywhere?Thanks!   
  It depends on the kind of context you create. If you create a forward compatible context, then certain GL functions will generate a GL error according to the spec. As for the GLU tesselator, this is just a software routine that doesn't use GL. You can even use it with Direct3D.
