Add to ORKGNonuniform sampling of images is a useful technique in computer graphics, because a properly designed pattern of samples can make aliasing take the form of high-frequency random noise. In this paper, the tech-nique of nonuniform sampling is extended from two dimensions to include the extra parameter dimensions of distribution ray tracing. A condition for optimality is suggested, and algorithms for approximating opti-mal sampling are developed. The technique is demonstrated at low sampling densities, so the characteris-tics of aliasing noise are clearly visible. At supersampling rates, this technique should move noise into fre-quencies above the passband of the pixel-reconstruction filter
