Image rendering using deterministic techniques with recursive rotation for sample point generation

摘要

The computer graphics system generates the pixel value of the pixel in the image, the pixel represents a point in the scene. Computer graphics system generates the evaluation of the integral for the function selected pixel values. Computer graphics system, and a function evaluation means and the sample point generation means. Sample point generator is configured to generate each set of sample points associated with one of a series of examples in each track of the embodiment configured to have tracking multiple levels. Example in one level can be divided into a plurality of rays, each ray is associated with at least Rei instance identifier. Sample point generator is configured to generate the sample points as low discrepancy amount column deterministic predetermined rotation operator selected for each level is applied recursively. Is configured to generate the function values ​​that are representative of each evaluation function that is in one selected sample points generated by the sample point generator, the function evaluation means, the function values ​​to generate a pixel value I use the. In one embodiment, a rotation operator selected are Cranleigh-Patterson rotation operator.
