US Patent 7782334 Pixel shader-based data array resizing

Systems and methods for performing data array resizing using a graphics processor resize a source data array of any dimensions to produce a destination data array of other dimensions. A pixel shader program may be used to configure the graphics processor to sample and filter the source data array to produce the destination data array. One or more destination data arrays may be mip maps of the source data array. A box filter or other type of filter may be used to produce each destination data array. Each pixel in the destination data array is produced in isolation, i.e., independently, thereby permitting the use of parallel processing to produce each pixel in the destination data array.
