Abstract

Experimental results are reported for a three-space hidden-surface removal approach that supports signal-return modelling by analysing objects represented as triangular nonpenetrating flat plates. The system employs boundary-traversal algorithms to replace each partially obscured surface with a set of triangular plates that constitute its visible portions. The inaccuracy of floating point computations can prevent the system from obtaining a flawless analysis of a model from a given perspective.
