Syntax

public class ConformingDelaunayTriangulationBuilder

Properties

Constraints

Sets the linear constraints to be conformed to. All linear components in the input will be used as constraints. The constraint vertices do not have to be disjoint from the site vertices. The constraints must not contain duplicate segments (up to orientation).

Declaration

public Geometry Constraints { set; }

Property Value

Type	Description
Geometry

Tolerance

Sets the snapping tolerance which will be used to improved the robustness of the triangulation computation. A tolerance of 0.0 specifies that no snapping will take place.

Declaration

public double Tolerance { get; set; }

Property Value

Type	Description
double

Methods

GetEdges(GeometryFactory)

Gets the edges of the computed triangulation as a MultiLineString.

Declaration

public MultiLineString GetEdges(GeometryFactory geomFact)

Parameters

Type	Name	Description
GeometryFactory	geomFact	The geometry factory to use to create the output

Returns

Type	Description
MultiLineString	the edges of the triangulation

GetSubdivision()

Gets the QuadEdgeSubdivision which models the computed triangulation.

Declaration

public QuadEdgeSubdivision GetSubdivision()

Returns

Type	Description
QuadEdgeSubdivision	The subdivision containing the triangulation

GetTriangles(GeometryFactory)

Gets the faces of the computed triangulation as a GeometryCollection of NetTopologySuite.Triangulate.Polygon.

Declaration

public GeometryCollection GetTriangles(GeometryFactory geomFact)

Parameters

Type	Name	Description
GeometryFactory	geomFact	the geometry factory to use to create the output

Returns

Type	Description
GeometryCollection	the faces of the triangulation

SetSites(Geometry)

Sets the sites (point or vertices) which will be triangulated. All vertices of the given geometry will be used as sites. The site vertices do not have to contain the constraint vertices as well; any site vertices which are identical to a constraint vertex will be removed from the site vertex set.

Declaration

public void SetSites(Geometry sites)

Parameters

Type	Name	Description
Geometry	sites

Remarks

The geometry from which the sites will be extracted.
