I don't understand how to apply culling in my opengl application. I understand what is the concept, but not the how to. First off, what is the difference betwenn GL_FRONT and GL_CW? To make culling properly, do I need to order my vertices' position clockwise or to order the indices? What is the reference of clockwise (i.e. is it when I face the -z axis or something else?
Thanks a lot,
