v0.4.0

Version 0.4.0

Multiple frontends and features:

• igexplorer Frontend for glare evaluation
• igview Interactive frontend for scene exploration
• igcli Command-Line tool for final renders
• igutil Command-Line tool to convert between images
• igevalglare Command-Line tool for glare evaluation (experimental)
• igbsdfinspector Basic viewer for Klems and Tensor BSDFs (experimental)
• Python API using Python 3.8 and above
• Blender extension
• Cuda accelerated
• Denoising with Intel Open Image Denoise (v2.3.1)

Highlights

• The interactive frontends moved from SDL2 to GLFW and OpenGL, which removes a
  runtime dependency and fixes the window handling on all platforms.
• Experimental path guiding, including a one-lobe vMF variant, sun-focused
  guiding and learned guiding for environment maps.
• Glare evaluation is now part of the runtime and no longer depends on the
  color space of the input.
• Reworked AOV handling with support for mono AOVs.
• The Python module is built against the stable ABI, so a single wheel works
  for Python 3.8 and above.
• Ignis falls back to the CPU when a GPU target fails to initialize.
• Hardened scene loading: the glTF, PLY, Klems, TensorTree and serialized mesh
  parsers now reject malformed and out-of-range input instead of reading past
  their buffers.
• Several correctness fixes for TensorTree and Klems BSDFs, validated against
  Radiance.

Download

This release has a binary for Windows with CUDA support included. You can
download the installer version (.exe).

Status

This is the first release built and published automatically from a version tag.

Progressive photon mapping is currently disabled and the guiding techniques are
experimental. As always, expect rough edges.

Workshop 2024

Version 0.3.6 (Workshop 2024)

A specific release for the 2024 workshop.
