MoonRay is DreamWorks Animation’s in-house 3D renderer, used to render all DreamWorks movies since How To Train Your Dragon: The Hidden World.

LuxCoreRender is a physically based and unbiased rendering engine. Based on state of the art algorithms, LuxCoreRender simulates the flow of light according to physical equations, thus producing realistic images of photographic quality.

Malt is a fully customizable real-time rendering framework for animation and illustration. Designed as a community effort to expand the possibility space of 3d rendering, it provides graphics programmers and technical artist an enjoyable “shadertoy-like” workflow inside Blender...

appleseed is a modern, open source, physically-based rendering engine designed to produce photorealistic images, animations and visual effects.

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.

Mitsuba is a research-oriented rendering system for forward and inverse light transport simulation. It consists of a core library and a set of plugins that implement functionality ranging from materials and light sources to complete rendering algorithms.

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.

PhotoRealistic RenderMan, or PRMan for short, is a proprietary photorealistic RenderMan-compliant renderer.

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).

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.
