TL;DR: The Sorted Pipeline Composition algorithm is described, which reduces the amount of data that needs to be transferred by an order of magnitude and results in a frame rate that is at least twice as high as the widely used binary swap image composition algorithm.

Abstract: The core advantage of sort last rendering is the theoretical nearly linear scalability in the number of rendering nodes, which makes it very attractive for very large polygonal and volumetric models. The disadvantage of sort last rendering is that a final image composition step is necessary in which a huge amount of data has to be transferred between the rendering nodes. Even with gigabit or faster networks the image composition introduces an overhead that makes it impractical to use sort last parallel rendering for interactive applications on large clusters. This paper describes the Sorted Pipeline Composition algorithm that reduces the amount of data that needs to be transferred by an order of magnitude and results in a frame rate that is at least twice as high as the widely used binary swap image composition algorithm.

- 14 Apr 2008
TL;DR: This paper proposes an experimental study of an inexpensive off-the-shelf sort-last volume visualization architecture based upon multiple GPUs and a single CPU that competes very well with a mid-sized PC cluster, while it significantly improves performance compared to a single standard PC.

- 15 Jul 2007
TL;DR: This work proposes a workload distribution which significantly increases interactivity during the data analysis process and introduces an additional step into the conventional visualization pipeline before mapping the whole process onto system components to incorporate the respective benefits of high-performance computing and GPU-based computation into a single visualization framework.

TL;DR: PixelFlow is described, an architecture for high-speed image generation that overcomes the transformation and frame-buffer– access bottlenecks of conventional hardware rendering architectures and performs antialiasing by supersampling.
Image composition schemes for sort-last polygon rendering on 2D mesh multicomputers
TL;DR: Experimental results show that sort-last-sparse strategies are better suited than sort- last-full schemes for software implementation on a general purpose multicomputer system and interleaved composition regions perform better than coherent regions.
