Sorting whole objects cannot resolve intersecting surfaces or cycles where different pixels require different orders. Exact evaluation of the chosen compositing model needs more detailed handling, such as per-pixel fragment storage and sorting or depth peeling. Weighted blended order-independent transparency replaces ordered compositing with a bounded-memory approximation.
