Constructors
| Light | |
Surface properties at a point on an object's surface. Much of this is standard whitted-style illumination. Plain diffuse/specular suraces can be defined with Surface.
Reflection and Refraction have their own constructors. AdditiveLayers is a way of stacking textures such that the colors are added together.
Blend takes two textures and returns the result of cobining them.
Warp is a little stranger; it takes a ray and re-casts into a separate scene (or the same one, if you so choose).
mpreshade :: [Light] -> Ray -> SolidItem t (Material t) -> Rayint t (Material t) -> [(Color, Vec)]Source
Calculate light intensity and direction at the current ray intersection. We do this up front so we don't have to re-do the shadow tests when we evaluate multiple layered textures.
