|
EarClipping(IList<Point2D>, IList<IList<Point2D>>, bool) | Point2D loops constructor. |
|
|
EarClipping(string) | Loops contructor that loads the contours from a XML file generated by WriteXML method, for debugging purpose. |
| Name | Description | |

|
|
Equals(Object) | Determines whether the specified object is equal to the current object. (inherited from Object). |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (inherited from Object). |
|
|
GetHashCode | Serves as the default hash function. (inherited from Object). |
|
|
GetType | Gets the Type of the current instance. (inherited from Object). |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (inherited from Object). |
|
|
ToString | Returns a string that represents the current object. (inherited from Object). |
|
|
Triangulate(natureType) | Performs triangulation and output result in a ready to use Mesh entity. |
|
|
Triangulate(out Point2D[], out IndexTriangle[]) | Performs triangulation and output result in the ecVertices and ecTriangles arrays. |
|
|
WriteXML(string, IList<Point2D>, IList<IList<Point2D>>) | Write the EarClipping contours to an XML file for debugging purpose. |
|
|
WriteXML(string, List<IntPoint>, List<List<IntPoint>>) | Write the EarClipping contours to an XML file for debugging purpose. |
The following sample demonstrates how to triangulate two contours. The checkDir parameter is set to false because the contours are already
properly oriented.
Point2D[] outer = new Point2D[]
{
new Point2D(0, 0),
new Point2D(10, 0),
new Point2D(10, 6),
new Point2D(0, 6),
new Point2D(0, 0)
};
Point2D[] inner = new Point2D[]
{
new Point2D(2, 2),
new Point2D(2, 3),
new Point2D(6, 2),
new Point2D(2, 2)
};
EarClipping ea = new EarClipping(outer, new Point2D[][] { inner }, false);
Mesh m = ea.Triangulate(Mesh.natureType.MulticolorSmooth);
viewport1.Entities.Add(m, 0, Color.Coral);
