In this paper, we describe a method to create an approximate ray-traced stereoscopic pair by transforming a fully raytraced left-eye view into an inferred right-eye view. Performance results from evaluating several random scenes, which indicate that the second view in a stereoscopic image can be computed with as little as 5% of the effort required to ...

Discrete ray tracing, or 3-D raster ray tracing (RRT), which, unlike existing ray tracing methods that use geometric representation for the 3-D scene employs a 3-D discrete raster of voxels for representing the 3-D scene in the same way a 2-D raster of pixels represents a 2-D image, is discussed.

Ray tracing is a method to produce realistic images; it determines visible surfaces in an image at the pixel level (Appel, 1968; Kay & Greenberg, 1979; Whitted, 1980). Unlike the z-buffer and BSP tree, ray tracing operates pixel-by-pixel rather than primitive-by-primitive.

The NVIDIA® OptiX™ ray tracing engine is a programmable system designed for NVIDIA GPUs and other highly parallel architectures. The OptiX engine builds on the key observation that most ray tracing algorithms can be implemented using a small set of programmable operations.

ACM SIGGRAPH 2006 Sketches on - SIGGRAPH '06, 2006When brought into the anaglyphic format, the images leap out of the two-dimensional plane. Without the three-dimensional glasses, the images are a complex jumble of red and cyan lines on an abstracted surface. With the three-dimensional glasses, the scenes spring into an enveloping experience of vibratory depth.

Despite nearly universal support for the IEEE 754 floating-point standard on modern general-purpose processors, a wide variety of more specialized processors do not provide hardware floating-point units and rely instead on integer-only pipelines. Ray tracing on these platforms thus requires an integer rendering process.

AbstractA multiprocessor algorithm for ray tracing is described. The performance of the algorithm is analysed for a cubic and square array of processors with only local communication between near neighbours. Theoretical expressions for the speedup of the system as a function of the number of processors are derived.

The construction and refinement of a computer graphics scene is unacceptably slow when using ray tracing. We introduce a new technique to speed up the generation of successive ray traced images when the geometry of the scene remains constant and only the light source intensities and the surface properties need to be adjusted.

Proceedings of the 1994 symposium on Volume visualization - VVS '94, 1994
This paper presents an eficient ray tracing method for scenes containing volumetric as well as geometric data. A global illumination equation is developed for this method, which is able to capture in a single image both realistic eaects and practical volume rendering.

An iterative ray-tracing method described by T Smith is shown to give a divergent sequence of approximations in certain cases; when it converges it has only first order convergence according to Hartree's classification of iterative processes An iterative method which always gives second order convergence is described and the significance of the ...
