BoundingVolumeHierarchy()
BoundingVolumeHierarchy(objects: Array)
Create a BoundingVolumeHierarchy from a list of Object3D objects.
Methods
dispose()
.dispose(): undefined
Dispose the unmanaged resource.
update()
.update(obj: Object3D): undefined
Update the BVH with a new model.
remove()
.remove(obj: Object3D): undefined
Remove a model from the BVH.
intersect()
.intersect(ray: Object): Object
Intersect the given ray with the acceleration structure.
The input ray object should have the following properties:
ray.origin: Vector3
Origin of the ray.
ray.direction: Vector3
Direction of the ray.
ray.near: Number
Optional. Nearest distance of search.
ray.far: Number
Optional. Furthest distance of search.
The returned object has the following properties:
.name: String
Name of the first intersected object.
.distance: Number
Distance of the first intersection point.
At the event of missing intersection, it will return null;
