Chapter 18, Shader Normal-Buffy

This shader queiries the normal direction and gives one or the other color that you have set for each direction. This shader is perfect when you need to make something invisible on the backside or vice versa. If you use it and turn the camera partly to both normals, you will end up with a little trouble. So I cover an alternative for that.
