| PS3 Real-time Ray-tracing - 104 sec
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 - 3451 sec
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

| Cell Processor Ray-tracing - 39 sec
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.

| Elite Force Raytracing Demo II - 170 sec
This video shows improvements made recently to the raytracing demo of Raven Software's Star Trek Voyager: Elite Force, posted on August 23, 2007.
Besides an increase in raw ray tracing performance, an effort has been made to accelerate shading of surfaces. Quake 3's shader scripts are not interpreted anymore, but compiled to native code. This resulted in a nice speed boost when object with complex shaders cover large portions of the screen. Compiling shaders also enabled us to implement a vector shading pipeline using SSE extensions.
Right in the beginning of the video this is demostrated by flipping the 'tinting' switch. This results in pixels that passed through the faster vector shading pipeline to be colored red. Pixels rendered using mono shading remain unchanged. Vector shading requires an additional step to collect rays that hit objects sharing the same shader, which is currently done for 4x4 pixel blocks. Unchecking the 'group pixels by shader' switch falls back to a simpler model, where rays hitting the same triangle are processed together. In the video it is demonstrated that this results in less pixels passing through the vector pipeline. This is due to the fact, that rays that hit neighbouring triangles with the same surface shader are NOT processed together.
Large portions of the video are rendered with activated 'Pixel Doubling'. This means that the scene is rendered at a resolution of 320x240 and subsequently streched to 640x480. Disabling 'Pixel Doubling' results in rendering taking place at the full resolution.
The video was captured on 64-bit Xubuntu running on a single AMD Athlon X2 3800+ at a resolution of 640x480 pixels.

| Fast GPU Ray Tracing of Dynamic Meshes using Geometry Images - 122 sec
Using the GPU to accelerate ray tracing may seem like a natural choice due to the highly parallel nature of the problem. However, determining the most versatile GPU data structure for scene storage and traversal is a challenge. In this paper, we introduce a new method for quick intersection of triangular meshes on the GPU. The method uses a threaded bounding volume hierarchy built from a geometry image, which can be efficiently traversed and constructed entirely on the GPU. This acceleration scheme is highly competitive with other GPU ray tracing methods, while allowing for both dynamic geometry and an efficient level of detail scheme at no extra cost.
This video was rendered using GeForce 7800-era GPUs.
