Accumulation Buffer
A surface where multiple scenes can be added to before the surface is displayed.
Adaptive Learning
An artificial intelligence system that can re-program itself based on environmental factors and influences.
Affine Texture Mapping
The simplest form of texture mapping. The texture coordinates of a polygon are linearly interpolated across the polygon surface. This technique does not account for perspective and therefore produces swimming texture effects.
Affine Transformation
A combination of a set of linear transformations, usually stored in a single matrix. Affine transformations include rotation, scaling, translation and shear.
Aliasing
The effect produced when a complex image is put onto a display with a limited resolution. This effect is a product of downsampling. Examples include jagged looking lines in lower resolutions.
Anti-aliasing
This is the process that gets rid of the aliasing effect. A filtering process is normally used in the process that removes "jaggedness effect" produced by pixels.
Arc
A section of a circle that is measured in degrees or radians.
Backbuffer
A secondary surface where the current frame's graphics are stored before they are transferred to the primary display surface.
Backface Removal
See Backface Culling.
Bezier Curve
A curve that is generated from the creation of several control points.
Bezier Patch
See Bezier Surface.
Bezier Surface
A curved surface created from a mesh of control points.
DJGPP
A freeware C++ compiler for DOS created by DJ Delorie.
Module
a collection of data and routines that act on the data. It might also be a collection of routines that provides a cohesive set of services even if no common data is involved. Examples include a source file in C, a class in C++, a package in Ada, and a unit in some versions of Pascal.
PNG
Portable Network Graphics. A graphics format that was brought about due to the licensing disagreements conerning GIF and JPEG.
