Re: [pygame] Shaders and Examples not Working

Looks like you need to make a call to glutInit() at the start of InitGL. Won't run here without it. -FM On Thu, Oct 23, 2008 at 5:31 PM, Ian Mallett [EMAIL PROTECTED] wrote: I've condensed it down and ported it to pygame. http://www.geometrian.com/Programs/Tutorials/pygameshaders.zip Ian

Re: [pygame] Shaders and Examples not Working

Hi, yes, I noticed that for some reason my computer doesn't require this, but nearly everyone I've talked to seems to need it. Is there a reason why glutInit() is required on some computers and not on others? Ian

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

[pygame] Shaders and Examples not Working

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. A dynamically rendered cubic reflectionmapped object is complicated enough. So is a
