Texture mapping is a method for adding a separately defined texture (a bitmap or raster image), pattern or color to the surface of a computer-generated graphic or 3D model.

The use of texture-mapping allows fairly simple shapes to be given a very realistic appearance. For example, planar walls can have stone textures mapped onto them for a very convincing image of three-dimensional stone walls. This does not affect the smoothness of a surface. It is more like painting a picture onto a surface in a scene.

The process of texture mapping involves mathematical mapping of the texture from one domain to another. Depending on 3D World Device Coordinates (WDC), i.e., the X, Y, Z value of the surface to be mapped, texture mapping can be categorized as follows:

  • 1-D texture domain
  • 2-D texture domain
  • 3-D texture domain
