Three Mesh Bvh Versions Save

Changed

• Improved raycasting performancy by ~20% by avoiding use of the "arrayToBox" function internally.

Fixed

• ParallelMeshBVHWorker now generates a geometry index if it's required.
• Add support for the "indirect" option to both workers.
• Worker generators not guaranteeing that 100% progress would be fired to the onProgress callback.

Fixed

• StaticGeometryGenerator, VertexAttributeTexture now support empty geometry.

Fixed

• MeshBVHHelper not updating correctly

Added

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

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.

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.

Changed

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

Fixed

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

Fixed

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

Added

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

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.
