U V W

‘ UVW (mapping) is a mathematical technique for coordinate mapping used in 3D computer graphics. The UVW (mapping) is suitable for painting an object’s surface based on a solid texture. Like the standard Cartesian coordinate system, it has three dimensions; the third dimension allows texture maps to wrap in complex ways onto irregular surfaces. Each point in a UVW map corresponds to a point on the surface of the object. The graphic designer or programmer generates the specific mathematical function to implement the map, so that points on the texture are assigned to (XYZ) points on the target surface. Once the texture is finished, all that has to be done is to wrap the UVW map back onto the object, projecting the texture in a way that is far more flexible and advanced, preventing graphic artifacts that accompany more simplistic texture mappings such as planar projection. For this reason, UVW mapping is commonly used to texture map non-platonic solids, non-geometric primitives, and other irregularly shaped objects, such as characters and furniture. ‘ (source wikipedia)
