To make a lighting system for a voxel game, I need to specify a darkness value per vertex. I'm using GL_COLOR_MATERIAL and specifying a color per vertex, like this:
glEnable(GL_COLOR_MATERIAL);
glBegin(GL_QUADS);
glColor3f(0.6f, 0.6f, 0.6f);
glTexCoord2f(...);
glVertex3f(...);
glColor3f(0.3f, 0.3f, 0.3f);
glTexCoord2f(...);
glVertex3f(...);
glColor3f(0.7f, 0.7f, 0.7f);
glTexCoord2f(...);
glVertex3f(...);
glColor3f(0.9f, 0.9f, 0.9f);
glTexCoord2f(...);
glVertex3f(...);
glEnd();
This is working, but with many quads it is very slow.. I'm using display lists too. Any good ideas in how to make vertices darker?
