YafaRay (was YafRay) is a powerful raytracer.
It enables users to create fantastic images and animations of a photorealistic quality.
It is an advanced raytracing rendering system with many modern features including full radiosity and High Dynamic Range Imaging (HDRI) for scene lighting. It reads a simple XML-based scene definition file, and can be used as a renderer for Blender.
Key Features
- Render
- Full Global Illumination – uses global illumination to produce realistically lit renderings of 3D scenes, using Monte carlo-derived approximations.
-
- Skydome Illumination – based mainly on light coming from an emitting sky, taking into account the soft shadows calculations also involved.
-
- HDRI Illumination.
-
- Caustics – uses photon mapping that allows for caustic (light distortion produced by reflection or transmission such as through a burning-glass).
-
- Real Depth of Field.
-
- Glossy/Blurry reflections.
- Modular framework.
- Integration in 3D suites via plugin.
- Distributed and multi-thread rendering.
