....The sort last method makes the load balancing problem easier since screen space constraints are removed. However, compositing hardware is needed to combine the output of the various processors into a single correct picture. Such approaches have been used since the 60 s in single display systems [2, 3, 8, 16, 17, 21], and more recent work includes [7, 9] The Metabuffer is a sort last multi display image compositing system with several unique features such as multi resolution and antialiasing [1] A very similar project, though currently without stressing multi resolution support, exists at Stanford ....

....needed to combine the output of the various processors into a single correct picture. The hardware must also assure that the quality of the composite image is similar to the image quality produced by the individual renderers. Such approaches have been used since the 60 s in single display systems [3, 6, 11, 12, 5, 14], and more recent work includes [8] 3 Our Approach We have chosen to implement a sort last scheme with several unique features. We will provide a uniform display space across a scalable number of projection displays, thus allowing any processor in our parallel system to have equal access to all ....

....ordering and inter object ordering using separating planes. 28 A later system was proposed by Cohen and Demetrescu [Deme80] which used processors implemented in VLSI. The processors were arranged in a pipeline, and compared depth values. This idea was extended in the system proposed by Weinberg [Wein81] to support anti aliasing using a variant of the A Buffer algorithm [Carp84] Instead of outputting a single z and RGB pair, each processor outputs a sequence of polygon fragments consisting of those objects that overlap the pixel. The compositor then merge these lists of fragments. Fragments that ....

....subset of the primitives to be rendered, and may generate pixels in any portion of the screen. Both vertical parallelism and image parallelism have been successfully employed in many systems, both research [6, 7, 8, 9, 24] and commercial [1, 2, 16] Object parallelism has received some attention [13, 14, 18, 20, 23], but has neither received the attention nor implementation that image parallelism has received, in spite of apparent advantages. We plan to explore the tradeoffs between object and image parallel in future forums, but briefly: ffl As image parallel machines scale, each processor has fewer and ....
