“…Further research could be extended to build special hardware mechanisms, similar to those reported in [Fuch81,Mont97,Winn97,Schn98] to yield even higher performance using the adaptive supersampling approach. For implementation details of the proposed renderer, readers are advised to refer to Lin's thesis [Lin98].…”

This paper presents the design and performance of a new parallel graphics renderer for 3-D images. This renderer is based on an adaptive supersampling approach that works for time/space-efficient execution on two classes of parallel computers. Our rendering scheme takes sub-pixel supersamples only along polygon edges. This leads to a significant reduction in rendering time and in buffer memory requirement. Furthermore, we offer a balanced rasterization of all transformed polygons. Experimental results prove these advantages on both a shared-memory SGI multiprocessor server and a Unix cluster of Sun workstations. We reveal performance effects of the new rendering scheme on subpixel resolution, polygon number, scene complexity, and memory requirements.The balanced parallel renderer demonstrates scalable performance with respect to increase in graphics complexity and in machine size. Our parallel renderer outperforms Crow's scheme in benchmark experiments performed. The improvements are made in three fronts: (i) reduction in rendering time, (ii) higher efficiency with balanced workload, and (iii) adaptive to available buffer memory size. The balanced renderer can be more cost-effectively imbedded within many 3-D graphics algorithms, such as those for edge smoothing and 3-D visualization. Our parallel renderer is MPI-coded, offering high portability and cross-platform performance. These advantages can greatly improve the QoS in 3-D imaging and in real-time interactive graphics.

This paper introduces an interactive volume visualization tool suite, the High Performance Medical Visualization tool Suite (HPMVS). The suite of tools is designed to aid medical staff in the assessment of renal disorders such as those caused by the von Hippel Lindau (VHL) Syndrome. The tools are useful for image-based evaluation of the severity and progression of disease and for planning and monitoring treatment. The configuration of HPMVS can provide near real-time visualization by allowing highly intensive computations to be computed on a supercomputer and less intensive computations and final display to be realized on a desktop workstation. Focus in this paper is on the exploration and extraction tools and the tool set configuration.

“…Aparece entonces una unidad segmentada de estructura SIMD que puede ser implementada de muy diversas formas: sobre transputers de INMOS [THEOH89] o sobre la Geometry Engine de Silicon Graphics [CLARK82]. Estas unidades tienen el inconveniente de quedar muchas veces vacías si la cadena de recortado resuelve que la primitiva o el punto a recortar debe ser rechazado o aceptado trivialmente en una etapa temprana [SCHEN98]. Por otro lado, la cantidad de planos de recortado suele ser pequeña, por lo que el tamaño de la tubería no es muy grande y el incremento de potencia no es elevado.…”
