'''Reflection''' in [[computer graphics]] is used to emulaterender [[reflection (physics)|reflective]] objects like [[mirror]]s and shiny surfaces.

Accurate reflections canare becommonly accomplishedcomputed e.g. by ausing [[Ray tracing (graphics)|ray tracetracing]] rendererwhereas 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. Approximateapproximate reflections can usually be computed faster by using simpler methods such as [[environment mapping]]. ReflectionReflections on a shiny surfacesurfaces like wood or tile can add to the photorealistic effects of a [[3D rendering]].
