ABSTRACT
We present an improved method of producing and manipulating deep pixel data which retains important surface information calculated during the execution of the rendering algorithm for later use during compositing, allowing operations normally performed in the renderer to be deferred until compositing. These include pixel-coverage calculation, pixel filtering, hard-surface blending, and matte object handling. Current methodologies for representing and transmitting deep pixel data work well for combining volumetric and hard-surface renders but are not very successful at combining hard-surfaces. By retaining additional surface information a renderer's final integration steps can be reconstructed later in compositing.

Compositing digital images
Most computer graphics pictures have been computed all at once, so that the rendering program takes care of all computations relating to the overlap of objects. There are several applications, however, where elements must be rendered separately, relying ...
