Changes include:

Lighting has changed significantly.

  • Several bugs have been fixed which caused light intensity to grow darker as the number of emissive meshes increased.
  • A bug which effected direct light visibility has been fixed. Previously, objects behind light sources would occasionally cast shadows
  • light intensity is now normalized by default, and surface area only influences light intensity if enabled GI light.use_surface_area
  • lights have an “exposure” which multiplies intensity by 2^exposure. This parameter can be used in combination with intensity to more effectively control light source power
  • dome lights are now explicitly sampled at each path vertex

Changes to mesh components

  • mesh.create_from_obj has been replaced with create_from_file, which includes a much larger variety of file formats

Changes to material components

  • alpha transparency is now enabled, and can be used for alpha cutouts, making transmission more clear, scivis applications, etc

Changes to camera components

  • create_perspective_from_fov has been renamed to create_from_fov
  • new simple create function which matches create_from_fov with some default parameters set

Changes to texture components

  • lots of new creation functions that can add and multiply two textures together
  • new create function to edit HSV of an existing texture
  • texture.create_from_image is renamed to create_from_file to match mesh component naming

Changes to global ViSII package

  • new register_pre_render_callback function for registering a python function that is called before the next frame
  • initialize_headless and initialize_interactive now merged into single initialize function
  • initialize can now be used to control the number of allocated components of each type
  • new enable/disable_updates functions to pause / resume asynchronous component uploads to the GPU. Useful for improving performance of bulk component creation
  • can now render texture_coordinates using render_data function

General changes

  • largely improved rendering performance
  • some changes to report more useful device side crash messages
  • deinitialize called automatically at exit if not done so already
