Abstract

Shadow mapping possesses an aliasing issue that is difficult to control. Recently a number of techniques, beginning with Perspective Shadow Maps have been proposed to choose the best possible 4 by 4 matrix for the light’s projection matrix. These new methods offer no guarantees of optimality, and can perform very poorly for some light configurations. Here we describe a method that chooses the 4 by 4 matrix using an optimization framework. We then describe numerical experimental results comparing our method to some of the previously suggested techniques.
