I know how: draw geometry with glDrawElements
Not know how: define normals with glNormalPointer
Not know how: define colors with glColorPointer
When I try glNormalPointer or glColorPointer, none of geometry looks correct. I not know if normals defined with each vertex, or with each face. If normals defined with each vertex, how do I if faces sharing vertex have separate colors… This is confusing of me. I ask that somebody can please help me?! I thank you.
