Question

I have a cube that I want to paint with same color on all six sides. I must use glColorMaterial() calls (or glMaterial() ?) in order for lights to work correctly. If I use
glColor4f() call then this does not work with lights.
Can some help with providing me with sequence of commands to paint all six sides with
(1,0,0,1) red color and 100% opacity? This must work in Android.

Answer 1

You can use glColorMaterial to set specify the material parameters that should track the current color. For instance, use

glEnable(GL_COLOR_MATERIAL)
glColorMaterial(GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE)

and then set the current color using glColor4f(...). Don’t forget the glEnable call!
