Hi, at one point they did work...
However pyopengl 3 is still in beta and has been changing a lot recently... causing some things to fail. There's been a recent fix in cvs to get them working on windows again (I think your platform). I know that recently a bunch of shader examples were added to cvs too. So... use pyopengl cvs, and help out with bug reports and patches :) Mike is pretty responsive over there, but if you have any patches I can apply them as well if you need. cheers, On Tue, Oct 21, 2008 at 1:42 PM, Ian Mallett <[EMAIL PROTECTED]> wrote: > Hi, > > I've been doing lots of cool stuff with PyOpenGL, but frankly, with cooler > effects comes more complexity, and when things get more complex, PyOpenGL > "fixed function" techniques do not seem to be the answer.
