This article lists common shading algorithms used in computer graphics. Interpolation techniques. These techniques can be combined with any illumination model:
A color wheel is a tool that provides a visual representation of the relationships between all possible hues. The primary colors are arranged around a circle at equal (120 degree) intervals. (Warning: Color wheels frequently depict "Painter's Colors" primary colors, which leads to a different set of hues than additive colors.)
Phong shading and the Phong reflection model were developed at the University of Utah by Bui Tuong Phong, who published them in his 1973 Ph.D. dissertation [3] [4] and a 1975 paper. [5] Phong's methods were considered radical at the time of their introduction, but have since become the de facto baseline shading method for many rendering ...
A shading language is a graphics programming language adapted to programming shader effects. Shading languages usually consist of special data types like "vector", " matrix ", "color" and " normal ".
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 ...
Flat shading is a simple shading model with a uniform application of lighting and color per polygon. [32] The color and normal of one vertex is used to calculate the shading of the entire polygon. [18] Flat shading is inexpensive, as lighting for each polygon only needs to be calculated once per render. [32]
The CPU sends instructions (compiled shading language programs) and geometry data to the graphics processing unit, located on the graphics card. Within the vertex shader, the geometry is transformed. If a geometry shader is in the graphics processing unit and active, some changes of the geometries in the scene are performed.
A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is black; if all are at maximum, the result is the brightest ...
