I am also using glGenBuffers and stuff, but glGenVertexArray and co. are supposed to allow to save the states of the vertex so I have not to call glVertexPointer and other vertex array related function for every frame. Another thing, with glBindBuffer(), if I use a constant like the one defined in the documentation, python doesn't know it, I have to postfix them with _ARB? Below is an example: glBindBuffer(GL_ARRAY_BUFFER_ARB, self.buffers[0]) Could it be that with my hardware this is an extension? Regards, Roland.
