Abstract
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.
