Re: I Played FarCry with Pixel Shader 3.0
Crystalline rocks will always have some specular part due to them, er containing crystals. Such as granite. Some metamorphic rocks would not show as much spectacular specular ( sorry, I had to to get that in , hoping to get rocks for brains in there as well later) such as limestone or slate unless wet
Albedo is a property that nobody has mentioned yet, ie how much light is absorbed or reflected. The moon has a low albedo so is quite dark though you would not know it of course looking at the sky.
I did all that without using Google, are you all impressed ? it's probably all the wrong way around !
