Adaptive Transparency

Adaptive Transparency

We introduce a new technique for real-time order independent transparency called Adaptive Transparency (AT) that closely approximates the ground-truth results obtained from A-buffer compositing but is 5x to 40x faster. The key contribution of Adaptive Transparency is the introduction of an adaptively compressed visibility representation that can be efficiently constructed and queried during rendering. It can be applied to a wide range of transparent geometry (e.g., foliage, windows, hair, and smoke). AT closely matches the ground-truth A-buffer solution and is both higher quality and faster than other approximate OIT techniques.
