glColor issues #549

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install trunk on Mac OS X Lion
2. run examples/graphics.py after changing line 94 to glColor3f(0.0, 1.0, 0.0)
3. You get a purple torus instead of a green one.

Paste in the traceback or error message:

Any additional info (platform/language/hardware) that may be relevant?

Nope. Same result on Snow Leopard, too.

I'm not sure why that glColor3f statement is in the code at line 94, as it 
doesn't actually do anything.  The color of the torus is being set with the 
later call to 

glMaterialfv(GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE, vec(0.5, 0, 0.3, 1))

If you want the glColor3f to affect the torus at all, you must first 
glEnable(GL_COLOR_MATERIAL).

Oops. Apologies. It's been a while since I used OpenGL directly without a lot 
of scaffolding to set up the scene for me, and I simply ignored the 
lighting/ambient section.
