Change Log Extracts

These are change-log extracts that might be useful with helping to update the documentation. There are some items still to be done, they're categorized, while items that have been completed are at the bottom of this page.

Photons

  1. Added multiple-thread support to photon shooting code. To take advantage of this at the moment, your scene will need multiple light sources.

Linux/Unix

  1. Linux: rework --benchmark. The built-in benchmark now accepts +L<path> command-line options and does no longer read any INI file but the provided one.
  2. Added preliminary Linux support for these two features
    • CPU timer; might return incorrect results depending on the platform.
    • signal catching (e.g. when aborting a render by hitting Ctrl+C).
  3. Added support for 'pause when done' in linux build.
  4. Added support for --benchmark on unix works together with +wt and print built-in features with --version
  5. Unix default file gamma changed from from 1.0 to 2.2.

Completed Items

Whats New

  • A platform independent change summary has been completed
  • The Windows change summary has been completed

Radiosity

  • Speed up radiosity pretrace option
  • Revival of Radiosity Load/Save
  • New radiosity "high reproducibility" mode
  • Radiosity maximum_reuse parameter
  • Added no_radiosity keyword
  • Implemented adaptive radiosity pretrace.
  • Parser now checks for plausible relation between radiosity minimum_reuse and maximum_reuse:

New Features

  • Diffuse backside illumination
  • Added a new list pattern type: cubic
  • Added a new warp type: cubic

  • chroma sub-sampling in JPEG output
  • Default output file type is now PNG
  • background alpha handling
  • sky_sphere with layered pigment and filter
  • Changed alpha handling for image file input and output
  • Changed input file gamma syntax for individual files
  • Added premultiplied BOOL parameter to input image file syntax
