Hello Daniel,
There is a good explanation of Surface normals, View
angles and Dot producs on Andy Jone's site http://www.pxl8.co.uk/ . It is not
exactly what you want but it may put you in the right
direction.

Onderwerp: A white to black materialHey everybody,
I'm wrecking my brain over building a material that looks white when you're looking at the surface, and as viewing angle decreses it turns to black. I know that's got to be simple, and might even exist already in RS, but I can't figure out how to calculate vectors and angles in VSL... :(The effect I'm after is to have a nice&shiny white object with clear definition that I hope results from black falloff.Sorry if this is confusing.Any ideas?Daniel
