Temporally Coherent Interactive Ray Tracing
Although ray tracing has been successfully applied to interactively render large datasets, supersampling pixels will not be practical in interactive applications for some time. Because large datasets tend to have subpixel detail, one-sample-per-pixel ray tracing can produce visually distracting popping and scintillation. We present an algorithm that directs primary rays toward locations rendere...
متن کاملInteractive Rendering with Coherent Ray Tracing
For almost two decades researchers have argued that ray tracing will eventually become faster than the rasterization technique that completely dominates todays graphics hardware. However, this has not happened yet. Ray tracing is still exclusively being used for off-line rendering of photorealistic images and it is commonly believed that ray tracing is simply too costly to ever challenge raster...
متن کاملInteractive Ray Tracing Client
In this paper we present an interactive GPU-based, GUI client, working with rendering server employing ray tracing based global illumination. The client is designed to guarantee interactivity (namely 1/60sec response time) no matter how slow the rendering server is. The client dynamically adjusts image resolution to match the server performance and complexity of the rendered scene. When the sce...
متن کاملInteractive Distribution Ray Tracing
Distribution ray tracing uses multiple samples per pixel to produce antialiased images that include soft shadows, glossy reflection, motion blur, and depth-of-field. The two main potential barriers to making distribution ray tracing interactive are that many rays might be required, and that those rays are not coherent enough to derive efficiency from tracing them in packets. A new interleaved s...
متن کاملBounded-Error Interactive Ray Tracing
Ray tracing, which computes radiance, is traditionally regarded as an off-line rendering algorithm that is too slow for interactive use. In this paper, we present an interactive system that uses 4D interpolants to approximate radiance, while providing guaranteed error bounds. Our system exploits the object-space, ray-space, image-space and temporal coherence in radiance to accelerate ray tracin...
