Abstract
A method for memory decomposition in a graphics rendering system with a pixel fragment memory includes tracking memory usage of the fragment memory to determine when a threshold is attained, and in response, separately rasterizing geometric primitives to smaller image regions. The system includes a pixel memory that can be hierarchically decomposed into smaller regions corresponding to a portion of the image currently being rendered. This hierarchical sub-division can be performed while rendering a scene and can be performed recursively to ensure that the capacity of the fragment buffer is not exceeded.
