In a distributed ray tracer, the sampling strategy is the crucial part of the direct lighting calculation. Monte Carlo integration with importance sampling is used to carry out this calculation.â€¦ (More)

Distribution ray tracing uses Monte Carlo integration to solve the rendering equation. This technique was introduced by Cook et. al, and was notable because of its simplicity and its ability toâ€¦ (More)

The details of doing a Monte Carlo direct lighting calculation are presented. For direct lighting from multiple luminaires, a method of sending one shadow ray per viewing ray is presented, and it isâ€¦ (More)

In many graphics tasks, such as pixel antialiasing, a set of spatially "uniform" samples must be generated on a unit square. Some algorithms attempt to create sets of samples whose x and yâ€¦ (More)
