'''Reflection''' in '''Computer Graphics''' is used to emulate mirrors and shiny surfaces.

==Mirror Reflection==

- '''Specular Reflection''' is added to surfaces in [[Ray Trace|Ray Tracing]] to give them a shiny, realistic appearance.

Mirror reflection is accomplished in a [[Ray Trace]] renderer by following a ray from the eye to the mirror and then calculating where it bouces from, and continuing the process until no surface is found, or a non-reflective surface is found.

==Specular Reflection==

- The image on the right has reflection on the floor and back wall.

[[Specular Reflection]] is the mirror-like reflection of light from a surface. Specular Reflection on a shiny surface like tile, or a wood floor can add to the Photorealistic effects of a 3D rendering.
