Parallel Progressive Ray-tracing

Interactive-Rate Animation Generation by Parallel Progressive Ray-Tracing on Distributed-Memory Machines

We describe a dynamic load-balancing algorithm for ray-tracing by progressive refinement on a distributed-memory parallel computer. Parallelization of progressive ray-tracing for single images is difficult because of the inherent sequential nature of the sample location generation process, which is optimized (and different) for any given image. Parallelization of progressive ray-tracing when ge...

Vertex tracing - interaktives ray tracing durch adaptiv progressives Refinement im Objektraum

This dissertation presents an approach for interactive, physically exact simulation of specular reflections and specular refractions in virtual environments. The introduced approach is called Vertex Tracing and allows a hybrid rendering to add global illumination effects in traditional hardware rendering systems. The core of the Vertex Tracing is an adaptive progressive ray tracing. In contrast...

A Parallel Method For Progressive Radiosity

The quality of synthetic images depends, rst, on the quality of the modeling of the three-dimensional scene to visualize. More numerous are the speciied geometrical and optical details, more realistic is the result image. Unfortunately, such scene descriptions need a big amount of memory, and then they need a long time of computation. In order to deal with these restrictions, we propose a paral...

Interactive Ray Tracing on a Virtual Shared-Memory Parallel Computer

This paper describes the results of experiments with accelerated ray tracing on a virtual shared-memory parallel computer and attempts to determine whether this kind of architecture would be suitable for an interactive ray tracing system. The machine used, the Kendall Square Research KSR1, is described in sufficient detail for its novel features to be appreciated. The paper describes a new ray ...
