Surface Reflection Properties
•Light reflected depends on
–Incoming light from light sources or other objects (light
source type, color, potential occlusion…)
–Orientation of surface to that light
–Orientation of surface to the viewer, including potential
occlusion by other surfaces
–Material properties (color, roughness,
reflectivity…)
•Surface normals
–Defined for tiny planar
or curved “patches”
or curved “patches”
–Defines orientation
of surface
of surface
