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 texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture . They may be stored in common image file formats , referenced by 3D model formats or material definitions , and assembled into resource bundles .
Polynomial texture mapping may be used for detailed recording and documentation, 3D modeling, edge detection, and to aid the study of inscriptions, rock art [5] and other artefacts. [ 3 ] [ 6 ] It has been applied to hundreds of the Vindolanda tablets by the Centre for the Study of Ancient Documents at the University of Oxford in conjunction ...
A bitmap image/rendering resource used in texture mapping, applied to 3D models and indexed by UV mapping for 3D rendering. Texture space The coordinate space of a texture map, usually corresponding to UV coordinates in a 3D model. Used for some rendering algorithms such as texture space diffusion Transform feedback
In computer graphics, relief mapping is a texture mapping technique first introduced in 2000 [1] used to render the surface details of three-dimensional objects accurately and efficiently. [2] It can produce accurate depictions of self-occlusion, self-shadowing, and parallax. [3] It is a form of short-distance ray tracing done in a pixel shader.

This technique is used by Adobe Illustrator Live Trace, Inkscape, and several recent papers. [6] Scalable Vector Graphics are well suited to simple geometric images, while photographs do not fare well with vectorization due to their complexity. Note that the special characteristics of vectors allow for greater resolution example images.
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).
