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 ...
Texture mapping [1] [2] [3] is a term used in computer graphics to describe how 2D images are projected onto 3D models. The most common variant is the UV unwrap, which can be described as an inverse paper cutout, where the surfaces of a 3D model is cut apart so that it can be unfolded into a 2D coordinate space (UV Space).
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).
The lower left image shows a scene with a viewpoint marked with a black dot. The upper image shows the net of the cube mapping as seen from that viewpoint, and the lower right image shows the cube superimposed on the original scene. In computer graphics, cube mapping is a method of environment mapping that uses the six faces of a cube as the ...
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
UVW mapping is a mathematical technique for coordinate mapping. [1] In computer graphics , it most commonly maps an object's surface in R 2 {\displaystyle \mathbb {R} ^{2}} to a solid texture with UVW coordinates in R 3 {\displaystyle \mathbb {R} ^{3}} , in contrast to UV mapping , which maps surfaces in R 2 {\displaystyle \mathbb {R} ^{2}} to ...

Multispectral image of Bek crater and its ray system on the surface of Mercury, acquired by MESSENGER, combining images at wavelengths of 996, 748, 433 nm. The bright yellow patches in other parts of the image are hollows. Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum.
