Abstract
A ray tracing method forms a first accumulation of importance values of non-clamped pixels in an image and forms a second accumulation of waste importance of clamped pixels in the image. The first accumulation and the second accumulation are applied to set an updated average sample count for pixels in the image, and the ray tracer generates a number of sampling rays for particular pixels by applying the updated average sample count to a per-pixel importance setting.
