ABSTRACT
Correctly rendering multi-layered transparent geometry requires accumulating contributions from multiple fragments per pixel. Dynamic A-buffers (e.g., Yang et al's [2010] per-pixel linked lists) achieve this by storing and sorting fragments on-the-fly. We introduce two improvements to recent GPU-based interactive A-buffer techniques. First, our redesigned algorithm uses fewer costly global atomic operations to construct linked lists. Second, we decouple visibility and shading to reduce memory demands of multi-fragment rendering.

A phenomenological scattering model for order-independent transparency
I3D '16: Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and GamesTranslucent objects such as fog, smoke, glass, ice, and liquids are pervasive in cinematic environments because they frame scenes in depth and create visually compelling shots. Unfortunately, they are hard to simulate in real-time and have thus ...
Moment-Based Order-Independent Transparency
Compositing transparent surfaces rendered in an arbitrary order requires techniques for order-independent transparency. Each surface color needs to be multiplied by the appropriate transmittance to the eye to incorporate occlusion. Building upon moment ...
Adaptive transparency
HPG '11: Proceedings of the ACM SIGGRAPH Symposium on High Performance GraphicsAdaptive transparency is a new solution to order-independent transparency that closely approximates the ground-truth results obtained with A-buffer compositing but, like a Z-buffer, operates in bounded memory and exhibits consistent performance. The key ...
