three-gpu-pathtracer - npm Package Versions

[0.0.23] - 2024.06.07

Added

• Support for CubeTexture environments and backgrounds.
• Material is compiled asynchronously to avoid blocking the browser. No rendering will occur until the material is ready.

Fixed

• Corner case where marking a mesh as non-visible would not remove the geometry.
• Meshes not updating when replacing the geometry with a new one.

[0.0.22] - 2024.05.03

Fixed

• Non visible meshes not being hidden when path traced.

[0.0.21] - 2024.04.29

Fixed

• Reverted transmission BRDF function changes resulting in black artifacts.

Added

• WebGLPathTracer class for more easily intializing a path tracer.
• Typescript definitions.

Changed

• PathTracingRenderer, DynamicPathTracingSceneGenerator, and more classes have been deprecated in favor of WebGLPathTracer. See new README for API.
• Remove IESLoader in favor of three.js' version.

[0.0.20] - 2024.02.21

Fixed

• Adjust peer dependency semver for three-mesh-bvh.

[0.0.19] - 2024.02.20

Fixed

• Ensure materials texture is never a degenerate dimension.
• Handle completely black environment maps so they do not corrupt the image.

[0.0.18] - 2024.02.20

Fixed

• Transparent textures no longer have the color incorrectly premultiplied by the alpha.
• Fix rounding error issue in tiled rendering logic causing some columns and rows of pixels to not be rendered to.
• Improve hdr map info to be able to handle any texture type.
• Path tracing scene generators no longer crash when an empty scene is provided.
• Native three.js spot light not working correctly.
• Env map clamping which was causing an incorrect circle of color to display at the poles.

Added

• Support for stratified sampling in addition to PCG and Sobol under the RANDOM_TYPE flag.

Changed

• Rendering objects with negative scales now requires three-mesh-bvh v0.7.2

[0.0.17] - 2024.01.18

Added

• Support for rendering geometry with inverted scales.

Changed

• Upgrade to three-mesh-bvh v0.7.0.
• AreaLights no longer render the light surface.
• Disabled sobol sampling functionality related to MacOS crashes. It can be re-enabled with the FEATURE_SOBOL define flag.

Fixed

• Models with a negative scale not rendering correctly.
• Renderer crashing on MacOS devices.
• Renderer crashing on Android devices.
• Rendering not working at all on iOS devices due to lacking support for linearly interpolated Float32 textures.

[0.0.16] - 2023-07-21

Fixed

• Reverted change that caused NaN values on some hardware.

[0.0.15] - 2023-05-20

Fixed

• Missing file extension.

Added

• CompatibilityDetector to determine whether the path tracer can run on the target platform.
• DEBUG_MODE define to PhysicalPathTracingMaterial to render out ray depth.
• GradientMapMaterial to map texture values to a color ramp.
• Support for copy function to ShapedAreaLight, PhysicalCamera, and PhysicalSpotLight.

Changed

• Fog hits no longer count as transparent surface bounces.
• Remove precision workaround for Equirect map.
• Significant refactoring to make more effective use of structs.

[0.0.14] - 2023-03-05

Added

• Support for volumetric fog material.
• Disable sampling of the environment map if env intensity is set to 0.0 to improve direct light sampling rate.

Changed

• Base color is now applied both on the way in and out of a transmissive material.
• Improved performance of env map CDF processing.

Fixed

• Area light shapes now consistently cast shadows in MIS and non MIS mode
