3.7.1 Changes Checklist

The following is a check list of the changes that need to be documented prior to version 3.7.1 release.

New Features

Materials:
  1. A new finish parameter use_alpha has been added to suppress highlights and reflections depending on pigment transparency.
  2. A new special pigment pattern user_defined has been added to define the pigment color directly in terms of a set of functions.
  3. A new pattern potential has been added to define a pattern based on the potential field of a blob or isosurface object.
  4. The map_type keyword now supports the Angular Map projection for light probes, popularized by Paul Devebec, as type 7
  5. Done Native support for repetition has been added to the crackle pattern to avoid the discontinuities in the pattern caused by repeat warps.
  6. Done The torus syntax has been extended to give more control over the spindle in a self-intersecting torus

  8. Fresnel angle-dependent attenuation can now also be applied to highlights and the diffuse component for more physical realism
Geometric Primitives:
  1. Done UV mapping support has been added to cones and cylinders
  2. A new parameter polarity has been added to isosurfaces to choose whether function values above the threshold should indicate the inside or outside
  3. Done A new geometric primitive lemon has been added

Scene Description Language, Options and INI settings

  1. Done Support for variable-size arrays has been added
