Placing Hidden Surface Removal within the CORE Graphics Standard: An Example.

Abstract

A Pascal based ACM proposed standard (CORE) graphics system from the University of Pennsylvania was converted to run on an 086/8087 microcomputer. Additionally, a non-restrictive full 3-D hidden surface removal algorithm for surfaces modelled by opaque polygons was implemented. This algorithm is an extension of the list priority algorithm created by Newell, Newell, and Sacha. By saving the priority list created by the algorithm from one batch of updates to the next, computational savings are possible. Although the present algorithm can only be used on raster type display surfaces, this algorithm could be used as a prelude to other scan line hidden surface removal algorithms to provide support for vector type displays.
