NetTopologySuite.Triangulate.ConstraintVertex Class Reference

A vertex in a Constrained Delaunay Triangulation. The vertex may or may not lie on a constraint. If it does it may carry extra information about the original constraint. More...

Public Member Functions
	ConstraintVertex (Coordinate p)
	Creates a new constraint vertex More...
Public Member Functions inherited from NetTopologySuite.Triangulate.QuadEdge.Vertex
	Vertex (double x, double y)
	Creates an instance of this class using the given x- and y-ordinate valuse More...
	Vertex (double x, double y, double z)
	Creates an instance of this class using the given x-, y- and z-ordinate values More...
	Vertex (Coordinate p)
	Creates an instance of this class using a clone of the given Coordinate. More...
override String	ToString ()
bool	Equals (Vertex x)
bool	Equals (Vertex x, double tolerance)
int	Classify (Vertex p0, Vertex p1)
Boolean	IsInCircle (Vertex a, Vertex b, Vertex c)
	Tests if this is inside the circle defined by the points a, b, c. This test uses simple double-precision arithmetic, and thus may not be robust. More...
double	CircumRadiusRatio (Vertex b, Vertex c)
	Computes the value of the ratio of the circumradius to shortest edge. If smaller than some given tolerance B, the associated triangle is considered skinny. For an equal lateral triangle this value is 0.57735. The ratio is related to the minimum triangle angle theta by: circumRadius/shortestEdge = 1/(2sin(theta)). More...
Vertex	MidPoint (Vertex a)
	returns a new vertex that is mid-way between this vertex and another end point. More...
Vertex	CircleCenter (Vertex b, Vertex c)
	Computes the centre of the circumcircle of this vertex and two others. More...
double	InterpolateZValue (Vertex v0, Vertex v1, Vertex v2)
	For this vertex enclosed in a triangle defined by three vertices v0, v1 and v2, interpolate a z value from the surrounding vertices. More...

Properties
bool	IsOnConstraint [get, set]
	Gets or sets whether this vertex lies on a constraint. More...
object	Constraint [get, set]
	Gets or sets the external constraint object More...

Additional Inherited Members
Static Public Member Functions inherited from NetTopologySuite.Triangulate.QuadEdge.Vertex
static double	InterpolateZ (Coordinate p, Coordinate v0, Coordinate v1, Coordinate v2)
	Interpolates the Z-value (height) of a point enclosed in a triangle whose vertices all have Z values. The containing triangle must not be degenerate (in other words, the three vertices must enclose a non-zero area). More...
static double	InterpolateZ (Coordinate p, Coordinate p0, Coordinate p1)
	Computes the interpolated Z-value for a point p lying on the segment p0-p1 More...
