Texture mapping originally referred to diffuse mapping, ... A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7]
Diffusion maps exploit the relationship between heat diffusion and random walk Markov chain.The basic observation is that if we take a random walk on the data, walking to a nearby data-point is more likely than walking to another that is far away.
By darkening areas of texture maps corresponding to corners, [citation needed] joints and recesses, and applying them via self-illumination or diffuse mapping, a radiosity-like effect of patch interaction could be created with a standard scanline renderer (cf. ambient occlusion).
However, by using a cube map the diffuse contribution from skylight illumination can be captured. Unlike environment maps where the reflection vector is used, this method accesses the cube map based on the surface normal vector to provide a fast approximation of the diffuse illumination from the skylight.
A more precise statement of the image acquisition process is that the image-intensities at each position are attenuated, depending on the strength (b-value) and direction of the so-called magnetic diffusion gradient, as well as on the local microstructure in which the water molecules diffuse. The more attenuated the image is at a given position ...

The Phong reflection model was developed by Bui Tuong Phong at the University of Utah, who published it in his 1975 Ph.D. dissertation. [1] [2] It was published in conjunction with a method for interpolating the calculation for each individual pixel that is rasterized from a polygonal surface model; the interpolation technique is known as Phong shading, even when it is used with a reflection ...
OBJ (or .OBJ) is a geometry definition file format first developed by Wavefront Technologies for The Advanced Visualizer animation package. It is an open file format and has been adopted by other 3D computer graphics application vendors.
