1. A method of rendering pixels from an abstract dataset, comprising: selecting a first collection of sub-pixel locations within a plurality of pixels, wherein the plurality of pixels are generated using at least one processor; sampling dataset properties at the selected sub-pixel locations; selecting a second collection of sub-pixel locations within the plurality of pixels, wherein said sub-pixel locations within the second collection are not the same as any of the sub-pixel locations within the first collection; merging the dataset properties of more than one of the selected sub-pixel locations within the first collection; storing the merged dataset properties at selected sub-pixel locations within the second collection; calculating pixel values based only upon the merged data properties stored at the sub-pixel locations within the second collection, wherein all sub-pixel locations are within the same plane.
