UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common ...
A Least squares conformal map (LSCM) is a 2-D representation of a 3-D shape created using the Least Squares Conformal Mapping Method. [ circular definition ] By using the map as a guide when creating a new 2-D image, the colors of the 2-D image can be applied to the original 3-D model.

Texture mapping [1] [2] [3] is a method for mapping a texture on a computer-generated graphic. "Texture" in this context can be high frequency detail , surface texture , or color . History
A sphere without bump mapping (left). A bump map to be applied to the sphere (middle). The sphere with the bump map applied (right) appears to have a mottled surface resembling an orange. Bump maps achieve this effect by changing how an illuminated surface reacts to light, without modifying the size or shape of the surface.
Relief mapping and parallax occlusion mapping are other common names for these techniques. Interval mapping improves on the usual binary search done in relief mapping by creating a line between known inside and outside points and choosing the next sample point by intersecting this line with a ray, rather than using the midpoint as in a ...
The origin of the term mipmap is an initialism of the Latin phrase multum in parvo ("much in little"), and map, modeled on bitmap. [4] The term pyramids is still commonly used in a GIS context. In GIS software, pyramids are primarily used for speeding up rendering times.
The example UV mapping given is a rather poor one, as it is just a projection of the sphere surface onto the x-y plane. This means that the top and bottom hemispheres will have the same UV coordinates. It would be much better to show an example UV mapping based on spherical polar coodinates (e.g. a latitude-longitude UV mapping).
