a relief map is a map that show on partial part of a state country etc.

In [[computer graphics]], '''relief mapping''' is an alternative [[texture mapping]] technique to [[parallax mapping]] that is much more accurate, and can support [[self-shadowing]] and [[normal mapping]]. It can be quite simply described as a short-distance [[Ray tracing (graphics)|raytrace]] done on a [[pixel shader]]; various techniques can be implemented to speed up the raytrace by taking variable step sizes.
