Method Detail

setMethod

public void setMethod(OBB.Method method)

Sets the method used to generate the OBBs within the tree. This setting will take effect upon to next call to build.

Parameters:

method - new method to be used to generate the OBBs

getRoot

public OBB 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[] elems,
                  int num)

Description copied from class: BVTree

Builds a bounding volume tree for a set of elements.

Specified by:

build in class BVTree

Parameters:

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

num - number of elements

recursiveRender

public void recursiveRender(Renderer renderer,
                            int flags,
                            BVNode node,
                            int level)

recursiveDepth

public int recursiveDepth(BVNode node,
                          int level)

getDepth

public int getDepth()

render

public void render(Renderer renderer,
                   int flags)

Description copied from class: BVTree

Render this object using the functionality of the supplied Renderer.

Specified by:

render in interface IsRenderable

Overrides:

render in class BVTree

Parameters:

renderer - provides the functionality used to perform the rendering.

flags - flags that may be used to control different aspects of the rendering. Flags are defined in Renderer and currently include Renderer.HIGHLIGHT and Renderer.SORT_FACES.

numNodes

public int numNodes()

Description copied from class: BVTree

Returns the number of nodes in this tree.

Overrides:

numNodes in class BVTree

Returns:

number of nodes in the tree

recursiveNumNodes

public int recursiveNumNodes(BVNode node)

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
