A Academic Ray Tracing to ilustrate a distributed computing graphic.

Raytracer.

The YveRT is a realtime raytracing library written in C.

Open Shading Language (OSL) is a small but rich language for programmable shading in advanced renderers and other applications. OSL is similar to C, as well as other shading languages, however, it is ... [More] specifically designed for advanced rendering algorithms with features such as radiance closures, BRDFs, and deferred ray tracing as first-class concepts. The OSL project includes a complete language specification, a compiler from OSL to an intermediate assembly-like bytecode, an interpreter that executes OSL shaders on collections of points in a SIMD manner, and extensive standard shader function library. These all exist as libraries with straightforward C++ APIs, and so may be easily integrated into existing renderers, compositing packages, image processing tools, or other applications. Additionally, the source code can be easily customized to allow for renderer-specific extensions or alterations, or custom back-ends to translate to GPUs or other special hardware. OSL is being developed by Sony Pictures Imageworks for use in its in-house renderer used for feature film animation and visual effects. The language specification was developed with input by other visual effects and animation studios who also wish to use it. This project still incubating within the warm halls of Sony Pictures Imageworks, although we are 100% committed to open sourcing it. The OSL language specification will be posted on this site within the next few weeks, and source code will follow soon after.

This project will develop a simple (read "Proof of concept") Raytracer in the scripting language Ruby. Main purposes * Learning more Ruby * Understanding more of implementing raytracing

Simple Ray Tracing engine created in Scala. It contains only ray-sphere intersections. You can specify texture to particular object. Bump mapping is also implemented, but just one simple function. ... [More] It's planned to implement texture-based bump mapping. [Less]

A ray tracer implemented on both CPU and GPU, taking advantage of multi-core platform

Fluid simulation based on smoothed particle hydrodynamics (SPH) is a practical method for the representation of liquids in interactive applications like virtual surgical training or computer games. In ... [More] recent years various papers introduced ideas for both, the SPH simulation and its visualization. This thesis explains detailed a straightforward CPU-executed implementation of the simulation, as well as an entirely GPU-executed visualization technique using isosurface raycasting, which allows the realtime rendering of multiple refractions. Theoretical foundations and alternative techniques are presented where it seems appropriate. [Less]

BRL-CAD is represented and developed by a consortium of individuals in the open source community from industry, academia, government, and private industry from all over the world. Our organizational ... [More] interests in BRL-CAD vary across the project's primary focus areas including computer-aided design (CAD), computer-aided manufacturing (CAM), solid modeling, and computer graphics. We have about a half-dozen core developers that are active on a daily basis with the project and several dozen community contributors, modelers, artists, and engineers. Our developers predominantly interact over IRC and through our various mailing lists. The BRL-CAD package is a powerful cross-platform open source solid modeling system that includes interactive solid geometry editing, ray-tracing support for rendering and geometric analysis, image and signal-processing tools, system performance analysis tools, a robust high-performance geometry engine, and much more. Currently standing at more than a million lines of code, 400 utilities, and hundreds of man-hours investment, BRL-CAD has more than 20 years of development history (since 1979) and is in production use by more than 2000 organizations around the world (this was our last statistic before we went open source and became untraceable). As useless bragging rights and fun statistics, the Ohloh source code statistics site recognized BRL-CAD as having "the world's oldest source code repository". Ohloh is a site that tracks the commit activity for more than 12,000 open source repositories performing in-depth historical analyses and commit tracking. When they reviewed the project histories for all projects in their database, BRL-CAD came in as the oldest project that has had continuous uninterrupted activity even edging out Emacs and GCC: http://www.ohloh.net/blog/worlds_oldest_source_code_repositories Released as open source software just a little over three years ago, BRL-CAD has received considerable attention from the CAD and solid modeling communities. We've had more than 230K downloads within last 12 months alone and our download rate is increasing. As far as we're aware, BRL-CAD is actually the only open source solid modeling system available with production-quality capabilities under an OSI-approved license. The BRL-CAD user-base is primarily composed of individuals in the CAD industry where the modeling requirements are fundamentally different to those of content modelers (e.g., Blender) that are used for animation, gaming, and film purposes. Where content modelers include commercial products like Maya, Softimage, and 3D Studio; BRL-CAD's primary competitors are in an entirely separate industry where commercial products like Unigraphics, Solidworks, Pro/Engineer, CATIA, and AutoCAD dominate. See for a visual overview of where BRL-CAD fits within the various CAD industries. Our goal is to become the best solid modeling system available by encouraging collaboration throughout the CAD communities, improving recognition that we're a production-quality F/OSS project, providing effective/better user-friendly tools, and by continuing to work hard at implementing the features needed by our users.
