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

==Approaches to reflection rendering==

For rendering environment reflections there exist many techniques that differ in precision, computational and implementation complexity. Combination of these techniques are also possible.

Mirrors are usually almost 100% reflective.
