3D Rendering

appleseed – physically-based global illumination rendering engine

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.
