three-mesh-bvh - npm Package Versions

[0.7.3] - 2024-02-20

Fixed

• StaticGeometryGenerator, VertexAttributeTexture now support empty geometry.

[0.7.2] - 2024-02-13

Fixed

• MeshBVHHelper not updating correctly

Added

• StaticGeometryGenerator now inverts geometry winding order when a mesh uses negative scales.

[0.7.1] - 2024-01-30

Fixed

• Minor case where outside bounds did not have floating point epsilon accounted for which could have resulted in missed intersections at the very edge of the bounds.
• The MeshBVHHelper( mesh, depth ) constructor not working as expected.
• The validateBounds function not accounting for the use of the "indirect" option.

Added

• Added new "ParallelMeshBVHWorker" that parallelizes MeshBVH generation across multiple WebWorkers. Falls back to a single threaded approach if SharedArrayBuffer is not supported.

[0.7.0] - 2024-01-15

Changed

• MeshBVHVisualizer has been deprecated and renamed MeshBVHHelper to align with three.js' conventions.
• MeshBVHHelper constructor now optionally takes a bvh.
• Organization of shader GLSL snippets. They are now grouped into the BVHSShaderGLSL object. Backwards compatible glsl snippets are provided for now but it's recommended to use the new location.

Fixed

• MeshBVHHelper will now display correctly regardless of parent in hierarchy.
• MeshBVHHelper.copy now correctly copies opacity, color.

[0.6.8] - 2023-10-08

Changed

• Small performance improvements to bvhcast function (up to ~10%).

[0.6.7] - 2023-09-07

Fixed

• GPU function parameters to fix undefined behavior on some platforms.

[0.6.6] - 2023-09-03

Fixed

• Case where indirect buffer with no index failed to raycast.

[0.6.5] - 2023-08-30

Added

• Added support for draw range so the BVH now implicitly respects the start and end range specified in the geometry.

[0.6.4] - 2023-08-28

Added

• An experimental "indirect" option to support an indirect triangle sorting for the BVH structure so the geometry index is not adjusted or implicitly generated.

Fixed

• Fixed estimateMemoryInBytes not testing for SharedArrayBuffers resulting in a smaller memory footprint.
• Fixed bug in "intersectsGeometry" function.

Removed

• Removed long deprecated shapecast code path using old function signature.
• Removed long deprecated serialization code path using old function signature.
• Removed long deprecated "terminate" function from web worker class.
