Method Detail

getRoot

public AABB getRoot()

Description copied from class: BVTree

Returns the root bounding volume for this tree

Specified by:

getRoot in class BVTree

Returns:

root bounding volume

build

public void build(Boundable[] elements,
                  int nelems)

Description copied from class: BVTree

Builds a bounding volume tree for a set of elements.

Specified by:

build in class BVTree

Parameters:

elements - elements around which this tree is to be built.

nelems - number of elements

update

public void update()

Description copied from class: BVTree

Updates the bounding volumes in this tree to ensure that they properly contain their enclosed elements. This should be called when the positions of the elements changes (such when the vertices of mesh change position).

Specified by:

update in class BVTree
