Re: [PyOpenGL-Users] gluBuild3DMipmaps

[Andrew W. <and...@al...>]

Hello,
  Great hack, got it working no problem now.  One side question,
gluBuild3DMipmaps works without a hitch, but when I call bool(glTexImage3D)
I get "False" back. glGetString(GL_VERSION) returns 2.0.1 so supposedly
teximage3d is supported on gl > 1.2.  Am I missing something here?
  Thanks
  Andrew
