Constructor Detail

DelaunayData

public DelaunayData()

Create a mesh data structure to collect points and edges that will be used by the Delaunay Triangulation

Method Detail

put

public void put(com.vividsolutions.jts.geom.Geometry geom,
                DelaunayData.MODE mode)
         throws IllegalArgumentException

Put a geometry into the data array. Set true to populate the list of points and edges, needed for the ContrainedDelaunayTriangulation. Set false to populate only the list of points. Note the z-value is forced to O when it's equal to NaN.

Parameters:

geom - Geometry

mode - Delaunay mode

Throws:

IllegalArgumentException

triangulate

public void triangulate()

getTriangles

public com.vividsolutions.jts.geom.MultiPolygon getTriangles()

get3DArea

public double get3DArea()

Return the 3D area of all triangles

Returns:

getTrianglesSides

public com.vividsolutions.jts.geom.MultiLineString getTrianglesSides()

Returns:

Unique triangles edges
