WebHowever, from the viewer's direction the back triangle is rendered clockwise if we draw it in the order of 1, 2 and 3 from the viewer's current point of view. Even though we specified the back triangle in counter-clockwise order, it is now rendered in a clockwise order. This is exactly what we want to cull (discard) non-visible faces!
