Abstract
The invention relates to a method of using a “bounds” comparator scheme and to a “bounds” comparator circuit. The method of using this scheme or comparator circuit allows a quick and easy test to characterize, utilizing a single floating-point bounds comparison function, the location of a point with respect to pre-defined end- points. The single floating-point bounds comparison function represents an additional instruction to be incorporated within computer instruction set architectures when performing trivial acceptance testing during the generation of three-dimensional images or graphics.
