texture mapping
Texture mapping is a method for mapping a texture on a computer-generated graphic. Texture here can be high frequency detail, surface texture, or color.
History
The original technique was pioneered by Edwin Catmull in 1974.

technique first introduced in 2000 used to render the surface details of three-dimensional objects accurately and efficiently. It can produce accurate depictions of
self-occlusion,
self-shadowing, and parallax.
It is a form of short-distance
ray tracing done in a
pixel shader. Relief mapping is highly comparable in both function and approach to another displacement texture mapping technique,
Parallax occlusion mapping, considering that they both rely on ray tracing, though the two are not to be confused with each other, as parallax occlusion mapping uses reverse heightmap tracing.
