WebThe octree color quantizationalgorithm, invented by Gervautz and Purgathofer in 1988, encodes image color data as an octree up to nine levels deep. Octrees are used because 23=8{\displaystyle 2^{3}=8}and there are three color components in the RGBsystem. WebFor exact results this requires storing all fragments before sorting and compositing. History. The A-buffer is a computer graphics technique introduced in 1984 which stores per-pixel lists of fragment data (including micro-polygon information) in a software rasteriser, REYES, originally designed for anti-aliasing but also supporting transparency. seattle university alumni association
