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
