Programming - The Surface class
The "Surface" class simply stores the details for any particular point on a texture. It has the following variables:
Vector normal - This stores the bump normal. Unless bump mapping is present in the
texture then this will be Vector(0, 0, 0).rgb color - This stores the color of the surface. This affects the color of any filtered
light due to transparency or refraction and also the diffusive color of the surface.double diffuse - This sets the diffusive level of the surface. 0 means no light is reflected diffusively
and 1 means that all the light is reflected diffusively.double transparency - This sets how much light passes straight through the surface.double reflect - This sets how much light is reflected.double refract - This sets how much light is refracted into the surface, ie glass/water.double ior - This is used alongside refract to set the index of refraction of the surface.
The "Surface" class doesn't have any special functions but has the arithmetic operators "+" and
"*" overloaded.
