i'm trying to use visionegg for displaying text screens. i have this
working if i approach the python code as a script.
for better software engineering, i've started to modularize my code
into
classes. when i do this, this weird error pops up:
AttributeError: 'module' object has no attribute 'GL_CLAMP_TO_EDGE'
The short answer:
Use the same hack as in VisionEgg.Core: gl.GL_CLAMP_TO_EDGE = 0x812F.
(Or, if it's possible, don't call the error-generating code until after
you have an instance of Screen open -- VisionEgg.Core will do it for
you, leaving your code hack-free.)
The long answer:
The current PyOpenGL is built for OpenGL 1.1 features. If I remember
correctly, GL_CLAMP_TO_EDGE came up in version 1.2. A better PyOpenGL
would be smarter about this kind of stuff, but for now, it's all we've
got.
Cheers!
