appleseed is a modern, open source, physically-based renderer developed by the VFX and Jupiter Jazz.
The application is ultimately targeted at production rendering.
appleseed is a renderer with a focus on quality and correctness. It is currently in a fairly early stage of development.
Features include:
- Fully spectral rendering pipeline (31 equidistant channels in the 400-700nm range, configurable at compile-time).
- Distribution ray tracing.
- Backward path tracing with or without next event estimation (explicit direct lighting).
- Forward path tracing (light tracing) with or without next event estimation.
- Progressive, interactive rendering.
- Multiple sampling frameworks available, configurable at compile-time.
- Multiple importance sampling.
- Camera motion blur with arbitrarily many transforms (show me, more).
- Ray traced deformation motion blur with arbitrary many motion segments per object (show me).
- Render layers.
- Ability to use arbitrarily large textures in constant memory budget (user-settable at runtime).
- Fully automatic, transparent color space conversions at runtime.
- Fully automatic, transparent gamma / inverse-gamma correction of textures and output frames.
- Highly scalable multithreaded rendering.
- Fast and robust ray tracing.
- Interactive rendering.
- Unidirectional path tracing.
- Mesh lights.
- Camera motion blur.
- Deformation motion blur.
- Render layers.
- PNG, Wavefront, OBJ, OpenEXR and Alembic file formats
- Modelling:
- Pinhole camera.
- Thin-lens camera (depth of field).
- Perfectly diffuse and perfectly specular BRDF.
- Ashikhmin-Shirley BRDF.
- Kelemen BRDF.
- Perfectly specular BTDF with Fresnel reflection.
- Perfectly diffuse EDF.
- Support for CIE XYZ, linear RGB, sRGB and spectral color spaces.
- Mesh lights (any geometry can emit light).
- Image-based lighting, with importance sampling of latitude-longitude maps.
- Support for geometry instancing (with per-instance materials).
- Support for non-physical surface shaders, and for mixing them with BSDF and EDF-based rendering.
- Possibility to add cameras, BSDF, EDF, lights, shaders without touching the core.
- 64-bit support on all major platforms.
