Improving Temporal Antialiasing with Adaptive Ray Tracing

Abstract

In this chapter, we discuss a pragmatic approach to real-time supersampling that extends commonly used temporal antialiasing techniques with adaptive ray tracing. The algorithm conforms to the constraints of a commercial game engine, removes blurring and ghosting artifacts associated with standard temporal antialiasing, and achieves quality approaching 16x supersampling of geometry, shading, and materials within the 16 ms frame budget required of most games.
