Method Detail

visitOrder

public BSPTreeVisitor.Order visitOrder(BSPTree<Euclidean3D> node)

Determine the visit order for this node.

Before attempting to visit an internal node, this method is called to determine the desired ordering of the visit. It is guaranteed that this method will be called before visitInternalNode for a given node, it will be called exactly once for each internal node.

Specified by:

visitOrder in interface BSPTreeVisitor<Euclidean3D>

Parameters:

node - BSP node guaranteed to have a non null cut sub-hyperplane

Returns:

desired visit order, must be one of BSPTreeVisitor.Order.PLUS_MINUS_SUB, BSPTreeVisitor.Order.PLUS_SUB_MINUS, BSPTreeVisitor.Order.MINUS_PLUS_SUB, BSPTreeVisitor.Order.MINUS_SUB_PLUS, BSPTreeVisitor.Order.SUB_PLUS_MINUS, BSPTreeVisitor.Order.SUB_MINUS_PLUS

visitInternalNode

public void visitInternalNode(BSPTree<Euclidean3D> node)

Visit a BSP tree node node having a non-null sub-hyperplane.

It is guaranteed that this method will be called after visitOrder has been called for a given node, it wil be called exactly once for each internal node.

Specified by:

visitInternalNode in interface BSPTreeVisitor<Euclidean3D>

Parameters:

node - BSP node guaranteed to have a non null cut sub-hyperplane

BSPTreeVisitor.visitLeafNode(org.apache.commons.math3.geometry.partitioning.BSPTree<S>)

visitLeafNode

public void visitLeafNode(BSPTree<Euclidean3D> node)

Visit a leaf BSP tree node node having a null sub-hyperplane.

Specified by:

visitLeafNode in interface BSPTreeVisitor<Euclidean3D>

Parameters:

node - leaf BSP node having a null sub-hyperplane

See Also:

BSPTreeVisitor.visitInternalNode(org.apache.commons.math3.geometry.partitioning.BSPTree<S>)

addContribution

private void addContribution(SubHyperplane<Euclidean3D> facet,
                             boolean reversed)

Add he contribution of a boundary facet.

Parameters:

facet - boundary facet

reversed - if true, the facet has the inside on its plus side
