Re: [Plib-users] Trouble making simple colored triangle

[Ben D. <be...@wa...>]

I spent more time trying to debug the problem, and have more information.
The reason that SSG seemed to be causing trouble is that inside ssgInit, it
enables GL_COLOR_MATERIAL.

What i discovered is that even if i disable GL_COLOR_MATERIAL afterwards,
geometry is still rendered incorrectly!  Instead of calling SSG, i tried
simply calling:

 glEnable(GL_COLOR_MATERIAL);
 glDisable(GL_COLOR_MATERIAL);

and was able to duplicate the white-object problem, thus it's not SSG's
fault.

The question remains why merely enabling and disabling this state messes up
rendering.  Perhaps it's a driver bug, but the Quadro is a pretty common
card.  Anyone have an idea?

Thanks,
Ben
