v0.0.3

Fixed

• Some black artifacts when rendering with depth of field.
• DynamicPathTracingSceneGenerator.reset not correctly resetting the class resulting in errors when calling "generate" again.

Changed

• Materials to use a texture instead of uniforms to cut down on max uniform errors.
• SUPPORT_DOF no longer needs to be explicitly set and will be toggled automatically based on the bokeh size parameter.
• Removed direct support for environment blur with addition of MIS. Instead use BlurredEnvMapGenerator to preblur an environment map.
• Antialiasing jitter is now performed per ray in the shader instead of via camera position jitter for improved AA.
• GRADIENT_BG define option to FEATURE_GRADIENT_BG

Added

• Support for "matte" material flag.
• Support for Multiple Importance Sampling for the envionment map and an associated "FEATURE_MIS" flag.
• BlurredEnvMapGenerator to blur environment maps.
• Support for rendering transparent backgrounds.

Removed

• Support for gradient environment colors. Use a DataTexture, instead.

New Demo Features

• Physically Based Models & Material Ball demos
  • Add support for toggling multiple importance sampling.
  • Use EnvMapGenerator to blur the environment maps.
  • Add support for setting background alpha.
  • Add new environment map options.
  • Add floor opacity slider.
  • Add support for "matte" materials rendering as transparent.

v0.0.2

Added

• Support for material sidedness which must be set explicitly on the material uniforms. See MaterialStructUniform.side for more information.
• DynamicPathTracingSceneGenerator to support skinned and morph target meshes.
• A PhysicalCamera instance and associated shader uniforms and updates to support camera depth of field and shaped bokeh.
• PathTracingSceneWorker as separate from the synchronous PathTracingSceneGenerator to support more build processes.
• Support for morph target, skinned meshes to scene generators.

Changed

• PhysicalPathTracingMaterial to have a "bounces" uniform rather than define.
• PathTracingSceneGenerator is now synchronous.

Fixed

• Case where material arrays did not work correctly.

Examples Added
