Run the shapecasting using three mesh bvh. This code is an adaption of the clipped edges example available in their repository. See https://github.com/gkjohnson/three-mesh-bvh/blob/a1665f35bc3b17f6832deb4aa9a7e422695dceec/example/clippedEdges.js#L322 for more info.

Parameters:

Name	Type
mergedGeometry	BufferGeometry
clippingPlane	Plane
positionAttribute	BufferAttribute | InterleavedBufferAttribute
cancelToken	CancelToken

Returns: number
