Abstract: A method for multiple rendering of an image includes selecting a level of detail (LOD) and selecting a set of offset biases based on the number of renderings. The offset biases are combined with the LOD resulting in processing biases. The processing biases are then truncated. The truncated bias values are then used as the basis of mipmap level processing for each rendering. The resulting renderings are then accumulated and sent to an output video device or additional image processor. Also, a computer system for carrying out the process may include multiple graphics processors containing registers, so that the offset biases can be rotated for each rendering between processors.
