Doug, I did find one problem in the spheres code. NVidia's GLSL compiler is clever enough to optimize away vertex attributes that aren't actually used in the linked shader program; this causes the "surface_color" attribute to disappear in the shader program that draws the textured sphere (which doesn't need a surface color, seeing as it uses a texture to color itself), and an OpenGL error gets raised when the code tries to set that attribute. That doesn't seem at all related to your framebuffer error, though. -Joe ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Factor-talk mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/factor-talk
