Design of an algorithm for the display of visible surfaces
- Univ. of Illinois, Urbana-Champaign, IL (United States)
Thesis. A visible surface algorithm capable of showing on a raster display smooth, transparent objects without jagged edges is described. The polygons defining the object to be displayed are put into visible order, and then output to the raster frame buffer by a special face drawing and shading algorithm. Very large objects or collections of objects can be manually put into visible order and Each group drawn separately; this allows scenes with more faces than can be held in the program data structure at any one time. Minimum hardware for implementation is a raster display with a frame buffer, and a minicomputer with a disk.
