Lots of parallel and distributed graphics systems are explored to solve this problem. However none of them is built for large-scale graphics applications.We designed AnyGL, a large-scale hybrid distributed graphics system, which consists of four types of logical nodes, Geometry Distributing Node, Geometry Rendering Node, Image Composition Node and Display Node. The first two types of logical nodes are combined to be a sort-first graphics architecture while the others compose images. A new state tracking method based on logical timestamp is also pro-posed for state tracking of large-scale distributed graphics systems. Besides, three classes of compression are employed to reduce the requirement of network bandwidth, including command code compression, geometry compression and image compression. A new extension, global share of textures and display lists, is also implemented in AnyGL to avoid memory explosion in large-scale cluster rendering systems.","PeriodicalId":90824,"journal":{"name":"Eurographics Symposium on Parallel Graphics and Visualization : EG PGV : [proceedings].

The major advantages of image-space partitioing are load balancing and low communication overhead, but processors require access to the full volume in order to render the volume with arbitrary views without frequent data redistributions. Subdividing the volume, on the other hand, provides storage scalability as more processors are added, but requires image compositing and thus higher communication bandwidth for producing the final image. In this paper, we present a parallel volume rendering algorithm that combines the benefits of both image-space and object-space partition schemes based on the idea of pixel and volume interleaving. We first subdivide the processors into groups. Each group is responsible for rendering a portion of the volume. Inside of a group, every member interleaves the data samples of the volume and the pixels of the screen. Interleaving the data provides storage scalability and interleaving the pixels reduces communication overhead. Our hybrid object- and image-space partitioning scheme was able to reduce the image compositing cost, incur in low communication overhead and balance rendering workload at the expense of image quality. Experiments on a PC-cluster demonstrate encouraging results.","PeriodicalId":90824,"journal":{"name":"Eurographics Symposium on Parallel Graphics and Visualization : EG PGV : [proceedings].

However, calculating adjacency graphs requires intensive memory space. For large data sets, the calculation becomes very inefficient on desk-top computers with limited main memory. In this article, an out-of-core method is presented for finding connectivities of large unstructured FEA data sets. Our algorithm composes of three stages. At the first stage, FEA cells are read into main memory in blocks. For each cell block read, cell faces are generated and distributed into disjoint groups. These groups are small enough such that each group can reside in main memory without causing any page swapping. The resulted groups are stored in disk files. At the second stage, the face groups are fetched into main memory and processed there one after another. Adjacency graph edges are determined in each face group by sorting faces and examining consecutive faces. The edges contained in a group are kept in a disk file. At the third stage, edge files are merged into a single file by using external merge sort, and the connectivity information is computed.","PeriodicalId":90824,"journal":{"name":"Eurographics Symposium on Parallel Graphics and Visualization : EG PGV : [proceedings].

However, due to inherent limitations of the rasterization approach many optical effects can only be approximated. For many products, in particular in the car industry, the resulting visual quality and realism is inadequate as the basis for critical design decisions. Thus the original goal of using virtual prototyping --- significantly reducing the number of costly physical mockups --- often cannot be achieved.Interactive ray tracing on a small cluster of PCs is emerging as an alternative visualization technique achieving the required accuracy, quality, and realism. In a case study this paper demonstrates the advantages of using interactive ray tracing for a typical design situation in the car industry: visualizing the prototype of headlights. Due to the highly reflective and refractive nature of headlights, proper quality could only be achieved using a fast interactive ray tracing system.","PeriodicalId":90824,"journal":{"name":"Eurographics Symposium on Parallel Graphics and Visualization : EG PGV : [proceedings].
