Hi,

I get (adding the necessary "import ctypes" at the top):
AttributeError: function 'glCreateShader' not found

Thanks,

You'll likely need to use the extension-based version (ARB.shader_objects). If you have a modern Nvidia/ATI card it will almost certainly have shader support available in an extension. Note that some older cards (e.g. integrated graphics chips) only support the lower-level APIs (i.e. you can't use GLSL with them).

BTW just tested this demo, it works fine with PyOpenGL bzr head (on Linux, with a reasonable Nvidia card):

HTH,

just FYI, it works also in windows ( win xp sp3 ), pyOpenGL-3.0.0b6, nvidia geforce 6600.
