Abstract:
A method for processing rendering data (V) for pixels defining a predetermined graphic, said rendering data (V) processed in parallel by dividing a two-dimensional image coordinate system into a plurality of pixel areas each composed of N pixels in a first direction and M pixels in a second direction perpendicular to said first direction, each of said plurality of pixel areas thus having a total of N.times.M pixels, said method comprising the step of:calculating variations of said rendering data with respect to said first and second directions, said variations used for interpolating values of said rendering data (V) for each of said pixels from predetermined apex data of said predetermined graphic;calculating an initial value (V0) of said rendering data on the side of said predetermined graphic by using the value of a predetermined apex data and said variation of said rendering data with respect to said first direction;calculating first N.times.M rendering data by using said initial value (V0) and said variations of said rendering data with respect to said second direction; andcalculating other N.times.M rendering data based on said variations of said rendering data with respect to said first direction and said second direction.
