Corona is a render engine for 3ds Max but the API is made to be accessible for other software as well. If someone wants to have a go at making a Blender plugin they can speak to the developer and get an SDK.
Some of the supported features are:
Full 3ds MAX integration Unbiased rendering with path tracing, light tracing, and bidirectional path tracing Biased rendering with irradiance cache, secondary cache, and regular/progressive photon mapping Corona material supporting: diffuse, reflection, refraction, translucency, opacity, bump mapping, displacement, emission, and anisotropy Physical sun & sky, area lights, and fast geometry lights Physically correct depth of field and motion blur simulation Progressive and bucket rendering modes Own simple and fast scattering and proxy plugins, custom texmaps
Major new features
- New Virtual Frame Buffer, with better desing and functionality
- Optional Light portals, for speeding up rendering of scenes with small windows
- Better system of artistic control fakes (selective visibility of objects)
- New robust algorithms for rendering caustisc (toy implementation, generally not usable in production):
- Bidirectional Path tracing
- Vertex Connection and Merging,
- Light tracing,
- Progressive Photon Mapping
- Windows Vista support (again)
- Option to autosave renders during and at the end of rendering
- GUI layout for settings and texmaps reworked
On a side-note they also have a benchmark ready so that you can test your CPU.
