The key contributionof our method is an adaptively compressed visibility representation that can be efficiently constructed and queried while rendering. The algorithm supports a wide range and combination of transparent geometry (e.g., foliage, windows, hair, and smoke). We demonstrate that adaptive transparency is five to forty times faster than realtimeA-buffer implementations, closely matches the image quality, and is both higher quality and faster than other approximate orderindependent transparency techniques: stochastic transparency, uniform opacity shadow maps, and Fourier opacity mapping.order independent transparencyvisibilitycompression10.1145/2018323.2018342119-126
