PS3 Real-time Ray-tracing IBM Interactive Ray-tracer (iRT) using three Sony Playstation3s (PS3) to render a model that is 75x more complex then those used in today's games. Ray-tracing is the rendering technique used by the film industry and is considered to complex for today's game systems. The code was written using IBM Cell SDK 2.0 on Linux. The iRT is totally scalable and only requires one Cell SPE to run. More PS3s = More SPEs = Higher client frame rates. All images are at least 720p 4x multi-sampled, with dynamic light sources, procedurally generated atmosphere, and dynamic shadows. Sorry about the bad camera microphone.

PhotoTechEDU Day 3: Ray Tracing, Lenses, and Mirrors Google Tech Talks January 31, 2007 ABSTRACT Photographic Technology Day 3: Ray Tracing, Lenses, and Mirrors In this lecture, we will study the principles of ray tracing for simple optical components: thin spherical lenses and spherical mirrors. The notion of real/virtual object and real/virtual images will be highlighted as well as the computation of the position and magnification the image. The case of thick lenses will also be mentioned including the notion of nodal and cardinal points. Credits: Speaker:Rom Clement Tags: google howto phototechedu day ray tracing |

Cell Processor Ray-tracing This video shows a progression of ray-traced shaders executing on a cluster of IBM QS20 Cell blades. The model comprises over 300,000 triangles and renders at over 60 frames per second, depending on the shader, at 1080p resolution using 14 Cell processors. Because of the scalable nature of the ray-tracer it can also render interactive frames on a single Linux Playstation3 using only 6 SPEs.

Ray Tracing Second Life Comparing the performance of a ray tracer written in LSL rendering a scene in Second Life when running first on the Mono and then the LSL2 virtual machines. When running on Mono the scene is rendered in 1/4 of the time. Tags: mono secondlife lsl ray trace virtualworld second life virtual world graphics rendering 3d |

Ray Tracing (Converging Lens) Ray tracing diagram for a converging lens, with the object beyond twice the focal length. (yes, the light actually bends at both surfaces, not the middle of the lens...)

Second Life - LSL Raytracer I wrote a raytracer entirely in LSL. It takes a scene in SL (simplifying it all into cubes due to limitations), and then draws it with nice lighting effects. For those who are interested, a more technical explanation of how it works (a knowledge of SL scripting and raytracing is assumed): The script first runs a sensor to get a list of objects in the scene, and grabs the bounding boxes of them. Then, for each pixel, a ray is shot out to detrmine where it collides, and how that area would be lit by the light source. So far only shadowing is implemented, but I should be able to implement phong, reflections, etc without too much extra work. Due to LSL being extremely slow, 64 different scripts are in the object to maximize speed. This video takes place in the main grid (where currently there is no Mono support). http://www.foxular.net/raytracer/ Has a bit more about raytracer, as well as various screenshots.

Ray Tracing on the GPU Part II I was playing around a little while longer, and am now using a texture to hold the location of all of the balls, so the balls can move around interactively.

Ray Tracing Iteratively Defined Objects (2004) This video demonstrates the application that utilizes the ray tracer to visualize higher dimensional Julia Sets, a technology that was developed at EVL. The voice over in the video explains the Ray Tracer technology and the mathematical complexities involved in the creation of the related visualization technology. Artists, scientists and mathematicians have been collaborating on a variety of projects at the Electronic Visualization Laboratory for over thirty years. In 1989, a ray tracer was created to visualize higher dimensional Julia Sets, involving and contributing to advances in all three previously mentioned fields.
