Introduction

This gem examines the results of an automated gradient search of optimized sampling patterns. The intent is to find a set of samples that perform better than other sampling patterns, yet require no evaluation as they are precomputed.

The present approach extends methods described in a previous gem (Chiu et al. 1994) whose introduction is restated below:

Monte-Carlo integration is often used to compute pixel values. For every pixel, a set of sample points is generated. The radiances of each point are then computed and averaged. To avoid aliasing, the sample points ...
