Direct send compositing for parallel sort-last rendering


Eilemann, S; Pajarola, R (2007). Direct send compositing for parallel sort-last rendering. In: Eurographics Symposium on Parallel Graphics and Visualization, Lugano, Switzerland, 20 May 2007 - 21 May 2007, 29-36.

Abstract

In contrast to sort-first, sort-last parallel rendering has the distinct advantage that the task division for parallel
geometry processing and rasterization is simple, and can easily be incorporated into most visualization systems.
However, the efficient final depth-compositing for polygonal data, or alpha-blending for volume data of partial
rendering results is the key to achieve scalability in sort-last parallel rendering. In this paper, we demonstrate
the efficiency as well as flexibility of the direct send sort-last compositing algorithm, and compare it to existing
approaches, both in a theoretical analysis and in an experimental setting.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
