Abstract

High quality shadows generated by shadow mapping is still an extensive problem in realtime rendering. This work summarizes some state-of-the-art techniques to achieve pixel accurate shadows and points out the various problems of generating artifact free shadows. Further a demo application has been implemented to compare the different techniques and experiment with alternative approaches.
