constructor
Creates a new block
Type Parameters
T
Parameters
minPoint: Vector3
defines the minimum vector (in world space) of the block's bounding box
maxPoint: Vector3
defines the maximum vector (in world space) of the block's bounding box
capacity: number
defines the maximum capacity of this block (if capacity is reached the block will be split into sub blocks)
depth: number
defines the current depth of this block in the octree
maxDepth: number
defines the maximal depth allowed (beyond this value, the capacity is ignored)
creationFunc: ((entry: T, block: OctreeBlock<T>) => void)
defines a callback to call when an element is added to the block
Parameters
entry: T
block: OctreeBlock<T>
Returns void
Returns OctreeBlock<T>

Returns void
intersects
Test if the current block intersect with the given ray and if yes, then add its content to the selection array
Parameters
ray: Ray
defines the ray to test with
selection: SmartArrayNoDuplicate<T>
defines the array to store current content if selection is positive
Returns void
remove
Remove an element from this block
Parameters
entry: T
defines the element to remove
Returns void
selectSearch playground for select
Test if the current block intersects the frustum planes and if yes, then add its content to the selection array
Parameters
frustumPlanes: Plane[]
defines the frustum planes to test
selection: SmartArrayNoDuplicate<T>
defines the array to store current content if selection is positive
Optional allowDuplicate: boolean
defines if the selection array can contains duplicated entries
Returns void
