three-mesh-bvh - npm Package Versions

[0.4.0] - 2021-06-11

Added

• MeshBVH.refit function to refit the bounds to modified vertices.
• setBoundingBox MeshBVH construction option.
• MeshBVH.getBoundingBox function.
• intersectsRange callback option to MeshBVH.shapecast.

Changed

• Removed src/worker/generateAsync.js function. Use GenerateMeshBVHWorker instead.
• Use type: module in package.json to enable use of es6 modules in node.
• Add sideEffects: false to package.json.
• Remove ability to generate an unpacked BVH.
• Improved "closestPointToPoint" performance slightly.
• MeshBVH.shapecast to take an object of callback functions instead of a list of function arguments and the triangle intersection callback has been changed to take a single triangle index. See README for new API. Calls using the old function will log a warning.

Fixed

• MeshBVHVisualizer not using the new geometry BVH if one was generated.
• MeshBVHVisualizer not using the new mesh if it was set.
• Case where passing in null intersectsTriangleFunc to MeshBVH.shapecast could throw an error.
• Case where the buffer being raycast against was not cleared correctly if a BVH had multiple roots.

[0.3.7] - 2021-03-06

Fixed

• Include built umd file including v0.3.6 changes.

[0.3.6] - 2021-03-03

Fixed

• Incorrect face index would be returned from intersection (related to three.js bug fixed in v0.126.1).

[0.3.5] - 2021-02-28

Fixed

• Case where raycastFirst failed to return a valid result.

[0.3.4] - 2021-02-25

Changed

• Raycast result to return a custom intersection object aligned with three.js v0.126.0.

[0.3.3] - 2021-01-24

Added

• depth argument to intersectsBoundsFunc and intersectsTriangleFunc of shapecast.
• "webvr" and "webxr" tags.
• closestPointToSegment function to the triangle object used during shapecast which can be used for capsule intersection detection.

[0.3.2] - 2020-12-23

Fixed

• Case where float 32 rounding error could result in leaf bounds not completely containing the triangles by expanding the bounds by an estimation of the error.

Changed

• Shapecast intersectsBoundsFunc to return one of the NOT_INTERSECTED, INTERSECTED, or CONTAINED constants. Returning true and false currently retains the old functionality.

[0.3.1] - 2020-12-14

Added

• Performance improvements when computing distance to geometry.
• shapecast to the docs.
• MeshBVHVisualizer to exports.

Fixed

• Cloning the bvh visualizer causing an error.
• Bug with shapecast function where one node would not be checked when using the node score function.

Changed

• Change the bvh visualizer so it automatically copies the local position and rotation of the target mesh.

[0.3.0] - 2020-12-01

Added

• generateAsync function in the /src/worker folder to help generate BVHs asynchronously with WebWorkers.

Changed

• three.js version to use v0.123.0, change Matrix4.getInverse to Matrix4.invert.

[0.2.0] - 2020-02-07

Added

• MeshBVH.serialize and deserialize functions so the bvh can be computed and transferred from a webworker.
• lazyGeneration (defaults to true) option for faster tree initialization.
• Support for a buffer-packed tree if lazyGeneration is false or a tree has been deserialized for a more smaller memory footprint.

Changed

• CENTER tree computation to improve raycast performance and create more balanced trees.
