    Presents three techniques for reconstructing lumigraphs/lightfields on commercial ccNUMA parallel distributed shared memory computers. The first method is a parallel extension of the software-based lightfield method proposed by M. Levoy and P. Hanrahan (1996). This expands the ray/two-plane intersection test along the film plane, which effectively becomes scan conversion. The second method extends... View full abstract»

    This paper reports the performance of a parallel volume rendering algorithm for visualizing a large-scale unstructured-grid dataset produced by a three-dimensional aerodynamics simulation. This dataset, containing over 18 million tetrahedra, allows us to extend our performance results to a problem which is more than 30 times larger than the one we examined previously. This high resolution dataset ... View full abstract»

  • Exploiting frame coherence with the temporal depth buffer in a distributed computing environment

    Publication Year: 1999, Page(s):29 - 116

    We introduce the notion of a parallel temporal depth buffer (or t-buffer) to speed up the rendering process for ray traced animations. The t-buffer is a conceptually simple data structure which stores knowledge about coherent pixel values across the duration of an animation. Through the use of this information, we can potentially avoid recomputing a significant number of redundant pixel values and... View full abstract»

    Rendering, in particular the computation of global illumination, uses computationally very demanding algorithms. As a consequence many researchers have looked into speeding up the computation by distributing it over a number of computational units. However, in almost all cases did they completely redesign the relevant algorithms in order to achieve high efficiency for the particular distributed or... View full abstract»

    This paper presents an interaction model to support collaborative scientific visualization. Relevant prior work is presented to contextualize the model and its import. An implementation of the model is presented within a collaborative system that supports flexible collaborative coupling of multi-user applications. An example application is presented to demonstrate the capabilities of the model. Th... View full abstract»

  • Interactive volume segmentation with the PAVLOV architecture

    We propose a new paradigm for interactive volume visualization which allows enhanced exploration of datasets through the use of real-time volume processing (e.g., segmentation) tightly coupled with rendering. We show examples of how this paradigm supports a new way of examining a dataset by providing interactive visual feedback to segmentation parameter adjustment. We have developed a hardware co-...

  • On the partitionability of hierarchical radiosity

    Publication Year: 1999, Page(s):69 - 78

    The hierarchical radiosity algorithm (HRA) is one of the most efficient sequential algorithms for physically based rendering. Unfortunately, it is hard to implement in parallel. There exist fairly efficient shared-memory implementations but things get worse in a distributed memory (DM) environment. We examine the structure of the HRA in a graph partitioning setting. Various measurements performed ... View full abstract»

  • Dynamic view-dependent partitioning of structured grids with complex boundaries for object-order rendering techniques

    Publication Year: 1999, Page(s):89 - 121

    Object-order rendering techniques present an attractive approach to run-time visualization of structured grid data, particularly when combined with a parallel rendering paradigm such as image composition. The ability of this combination to exploit hardware exceeds that of parallel image order methods. However, certain configurations of grid boundaries prevent composition from being performed corre...

  • Parallel accelerated isocontouring for out-of-core visualization

    We introduce a scheme for static analysis that allows us to partition large geometric datasets at multiple levels of granularity to achieve both load balancing in parallel computations and minimal access to secondary memory in out-of-core computations. The idea is illustrated and fully exploited for the case of isosurface extraction, but extendible to a class of algorithms based on a small set of ... View full abstract»
