Sunflow is an open source rendering system for photo-realistic image synthesis. It is written in Java and built around a flexible ray tracing core and an extensible object-oriented design. It was created as a framework for experimenting with global illumination algorithms and...
Pixie is an open source RenderMan renderer for generating photorealistic images. You can compile Pixie on Windows (using Visual Studio 2005), Linux and on OSX (using XCode or unix style configure script).
YafaRay is a free open-source montecarlo raytracing engine released under the LGPL 2.1 license. Raytracing is a rendering technique for generating realistic images by tracing the path of light through a 3D scene.

NOX Renderer is a rendering software based on unbiased methods.
The renderer is available as a standalone Windows executable with a plug-in to link it to 3ds Max.
A linking script is also available for Blender users.
As with other similar applications, such as Maxwell Render a.




MiniLight is a minimal global illumination renderer. It is primarily an exercise in simplicity. But that makes it a good base and benchmark (in some sense) for development and experimentation. And it just might be the neatest renderer around (on average, about 650 lines).




A free Terrain Synthesizer and RendererPicogen is an outdoor ray tracing system, a free Terrain Synthesizer and Renderer targeting large-scale terrain with realistic day/night-illumination and detailed plant populations.



OctaneBench® allows you to benchmark your GPU using OctaneRender. This provides a level playing field by making sure that everybody uses the same version and the same scenes and settings. Without these constraints, benchmark results can vary a lot.
Freestyle is a software for Non-Photorealistic Line Drawing rendering from 3D scenes. It is designed as a programmable interface to allow maximum control over the style of the final drawing: the user "programs" how the silhouettes and other feature lines from the 3D...




Octane Render is the world's first GPU based, un-biased, physically based renderer. What does that mean? It uses the video card in your computer to render photorealistic results fast...really fast. This allows the user to create stunning works in a fraction of the time of...




Tungsten is a physically based renderer I originally wrote in early 2014 for the Image Synthesis Rendering Competition at ETH, where it won 1st place with the image pictured above. It is intended for offline rendering in graphics research and is still in development, at least...

Thea Render is a state-of-the-art biased/unbiased renderer with a rich set of innovative features, a powerful material system and its own advanced studio, all-in-one. Plugins are available for 3dsMax, Blender, Cinema4D, Rhino, SketchUp and SoftImage.
