ABSTRACT:
A method for rendering graphical objects in a scene to generate a display images includes dividing the geometric primitives of models in a scene among portions or "chunks" of the view space to which the primitives will be rendered, and then rendering geometry referenced to the chunks in series in a common depth buffer. Geometry for a chunk can be rendered, including sophisticated anti-aliasing and translucency computations, using a minimum of memory. Serially rendering object geometry in chunks provides an effective form of compression because pixel fragments can be generated for one chunk at a time and then resolved. Pixel fragments can be resolved in a post-processing step for one chunk while primitives for another chunk are rasterized.
