Fragment processing
Encyclopedia
Fragment processing is a term in computer graphics
referring to a collection of operations applied to fragment
s generated by the rasterization operation in the rendering pipeline.
During the rendering
of computer graphics, the rasterization step takes a primitive, described by its vertex
coordinates with associated color
and texture information, and converts it into a set of fragment
s. These fragments then undergo a series of processing steps, e.g. scissor test, alpha test, depth test, stencil test, blending, texture mapping and so on. These steps are collectively referred to as fragment processing.

Fragment (computer graphics)
In computer graphics, a fragment is the data necessary to generate a single pixel's worth of a drawing primitive in the frame buffer.This data may include, but is not limited to:* raster position* depth...

Rendering (computer graphics)
Rendering is the process of generating an image from a model , by means of computer programs. A scene file contains objects in a strictly defined language or data structure; it would contain geometry, viewpoint, texture, lighting, and shading information as a description of the virtual scene...

Vertex (computer graphics)
A vertex in computer graphics is a data structure that describes a point in 2D or 3D space. Display objects are composed of arrays of flat surfaces and vertices define the location and other attributes of the corners of the surfaces.-Application to object models:In computer graphics, objects are...

Color
Color or colour is the visual perceptual property corresponding in humans to the categories called red, green, blue and others. Color derives from the spectrum of light interacting in the eye with the spectral sensitivities of the light receptors...
