Implements org.apache.commons.math3.geometry.partitioning.BSPTreeVisitor.visitInternalNode.

Doc from org.apache.commons.math3.geometry.partitioning.BSPTreeVisitor.visitInternalNode.

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.

Parameters
node:BSPTree<Sphere2D>

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

Parameters
node:BSPTree<Sphere2D>

leaf BSP node having a null sub-hyperplane

visitOrderback to summary
public BSPTreeVisitor.Order visitOrder(final BSPTree<Sphere2D> node)

Implements org.apache.commons.math3.geometry.partitioning.BSPTreeVisitor.visitOrder.

Doc from org.apache.commons.math3.geometry.partitioning.BSPTreeVisitor.visitOrder.

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.

Parameters
node:BSPTree<Sphere2D>

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

Returns:BSPTreeVisitor.Order

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