==Specular
[[Specular reflection]] is the mirror-like reflection of light from a surface. Specular reflection is accomplished in a [[Ray tracing|ray trace]] renderer by following a ray from the eye to the mirror and then calculating where it bounces from, and continuing the process until no surface is found, or a non-reflective surface is found. Specular reflection on a shiny surface like [[tile]], or a [[wood floor]] can add to the [[photorealistic]] effects of a 3D rendering.
==Diffuse
Most surfaces are too rough to reflect light specularly, and instead reflect in a random direction. In ray-tracing, this is harder to emulate than simple specular reflection{{fact}}.
