All Implemented Interfaces:

java.io.Serializable, Body, Bounds, SpatialHandle<T>

public class OcNode<T>
extends BoundingSphere
implements SpatialHandle<T>

A node used to define an object stored in the octree. This is not optimized for triangle level octrees, as the overhead per node is substantial.

OcNode

public OcNode()

OcNode

public OcNode(float x,
              float y,
              float z,
              float r,
              T o)

OcNode

public OcNode(Point3f c,
              float r,
              T o)

Builds an OcNode with the specified center, radius and object.

Parameters:

c -

r -

o -

OcNode

public OcNode(T o,
              VertexContainer source)

Builds an OcNode for the specified object. The bounds are determined using the source interface which allows an optimal sphere to be constructed.

Parameters:

o -

source -

Method Detail

getParent

public OcCell<T> getParent()

getObject

public T getObject()

Specified by:

getObject in interface SpatialHandle<T>

remove

public void remove()

Removes the node from its spatial container.

Specified by:

remove in interface SpatialHandle<T>

recompute

public void recompute()

Recompute the bounds for the object and place it in the spatial container in the correct place. This generally causes a removal and reintegration.

Specified by:

recompute in interface SpatialHandle<T>
