Abstract:
A scan conversion and hidden surface algorithm is discussed in detail. The algorithm is of the Watkins class but differs markedly in implementation. It is running on an 8k Varian 620 computer and is used to produce shaded color rendering of three-dimensional objects. Details of the data structure used and of the internal sortings is given. Together with a video disk subsystem, the mini-computer system is capable of producing studio-quality T.V. images in 3 to 20 seconds, depending on image complexity.
