Re: [PyOpenGL-Users] glTexImage2d size

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

Hello,
  You are correct, I would like to use textures that are not of power 2 in
dimension.  I have an Nvidia Quadro FX 3450 that mysteriously supports it.
I seem to have found a work around using the gluBuild2DMipmaps call, the
appear to automatically pad the image correctly.  I guess I should read the
documentation a little closer!
  Thanks
  Andrew
