It means that there are no alien vertices in the circumcircle of each triangle. The algorithm that is used is also known as incremental insertion. since:    2.4 version:    $Id: TriangulationFactory.java 28966 2008-01-27 17:36:43Z acuster $ author:    Jan Jezek Constructor Summary protected   TriangulationFactory(Quadrilateral quad, DirectPosition[] pt)      Constructs the TriangulationFactory. Method Summary public  List getTriangulation()      public  void insertPoint(DirectPosition newVertex)      Accommodate new vertex into the existing triangles. protected  List insertTriangles(List trian)      Decides whether to insert triangle directly or go throught delaunay test. protected  void recursiveDelaunayTest(List ChangedTriangles)      This is the test loop, that starts to tests of triangles until the result of insertation of triangle evokes changes in TIN. Constructor Detail TriangulationFactory protected TriangulationFactory(Quadrilateral quad, DirectPosition[] pt) throws TriangulationException(Code) Constructs the TriangulationFactory. Parameters:   quad - of location to be triangulated. Parameters:   pt - Array of points for triangulation. throws:   TriangulationException - when the vertices are outside of the specified quad. Method Detail getTriangulation public List getTriangulation()(Code) Set a List of points for triangulation TIN as list of triangles. insertPoint public void insertPoint(DirectPosition newVertex) throws TriangulationException(Code) Accommodate new vertex into the existing triangles. Parameters:   newVertex - new vertex throws:   TriangulationException - when newVertex is outside triangles insertTriangles protected List insertTriangles(List trian) throws TriangulationException(Code) Decides whether to insert triangle directly or go throught delaunay test. Parameters:   trian - if triangles to be inserted List of changed triangles throws:   TriangulationException - TriangulationException recursiveDelaunayTest protected void recursiveDelaunayTest(List ChangedTriangles) throws TriangulationException(Code) This is the test loop, that starts to tests of triangles until the result of insertation of triangle evokes changes in TIN.
