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 interfaceBSPTreeVisitor<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 interfaceBSPTreeVisitor<Euclidean3D>
- Parameters:
node
- BSP node guaranteed to have a non null cut sub-hyperplane- See Also:
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 interfaceBSPTreeVisitor<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 facetreversed
- if true, the facet has the inside on its plus side
-
getProjected
public PolygonsSet getProjected()
Get the projection of the polyhedrons set on the plane.- Returns:
- projection of the polyhedrons set on the plane
