We introduce multi-layer alpha blending, a novel solution to real- time order-independent transparency that operates in a single rendering pass and in bounded memory. The main contribution of our method is a new scalable approximation for the compositing equation that makes possible to easily trade off better image quality for more memory and lower performance. We demonstrate improved image quality and performance over previously published methods, while also reducing memory requirements.
