A pre-processing method prepares 3D objects for rendering to image layers in a layered graphics rendering pipeline. The method transforms a bounding volume for an object to a 2D bounding box in a 2D view space. It then subdivides the bounding box into blocks of image samples called chunks. To computer the portion of the object that should be rendered to each chunk, it determines which geometric primitives of the object overlap each chunk and generates a list of primitives to the rendered for each chunk.

[ We claim:] [1.]1. A method of dividing object geometry of a scene into chunks comprising:maintaining bounding volumes for objects in the scene;projecting the bounding boxes into a 2D view space to determine 2D bounding boxes for the objects, where the 2D bounding boxes are not aligned to screen coordinates of a display device;sub-dividing the 2D bounding boxes into chunks, where the chunks are 2D arrays of image sample coordinates that are not aligned to screen coordinates; anddetermining how the object geometry enclosed in the bounding boxes overlaps the chunks of corresponding 2D bounding volumes to produce a list of geometric primitives that overlap corresponding chunks.
