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,
                boolean isConstrained)
         throws org.jdelaunay.delaunay.error.DelaunayError

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 -

isConstrained -

Throws:

org.jdelaunay.delaunay.error.DelaunayError

put

public void put(com.vividsolutions.jts.geom.Geometry geom)
         throws org.jdelaunay.delaunay.error.DelaunayError

Put a geometry into the data array of points. If you want to build a constrained Delaunay triangulation, use the method put(Geometry geom, boolean isConstrained). Note the z-value is forced to O when it's equal to NaN.

Parameters:

geom -

Throws:

org.jdelaunay.delaunay.error.DelaunayError

getDelaunayEdges

public ArrayList<org.jdelaunay.delaunay.geometries.DEdge> getDelaunayEdges()

Gives the collection of edges

Returns:

getDelaunayPoints

public List<org.jdelaunay.delaunay.geometries.DPoint> getDelaunayPoints()

Gives the collection of points

Returns:
