Re: [PyOpenGL-Users] culling with tétrahedron

[Ian M. <geo...@gm...>]

Well, for one thing, you're drawing the tetrahedron in line mode.
GL_CULL_FACE does nothing for GL_LINE.

You might also try culling the front faces glCullFace(GL_FRONT).  If the
results are expected, then reverse the winding order of the polygons (i.e.,
polygon [v1,v2,v3] specify as [v1,v3,v2]) and cull the back as before.
