Abstract

Accurate perspective mapping in real-time requires costly division operations per pixel and therefore ap proximation techniques are often employed. These per mit the mapping to be performed by interpolation, but generally with a significant set-up cost for the computa tion ofthe parameters. An efficient approximation tech nique which achieves good results with modest set-up requirements is presented. The technique uses Cheby shev control points to minimise errors.
