ABSTRACT:
A computer-implemented method, apparatus, and article of manufacture provide the ability to store image data for use in a real-time compositing computer application. A storage tile size is determined based on disk input/output (I/O) hardware testing. A processing tile size is determined based on graphics I/O testing. An image is obtained and processing tiles (of the processing tile size) are mapped over the image. A center of the image is used as a point of origin for the processing tiles. The processing tiles are mapped to storage tiles. The storage tile point of origin is located at a lower left corner of the processing tiles. Each storage tile is configured to contain complete processing tiles that are stored in the storage tiles based on the storage tile size, processing tile size, and the mappings.
