DelaunayTri
Class: DelaunayTri
(Not recommended) Construct Delaunay triangulation
Compatibility
Note
DelaunayTri is not recommended. Use delaunayTriangulation instead.
Syntax
DT = DelaunayTri()
DT = DelaunayTri(X)
DT = DelaunayTri(x,y)
DT
= DelaunayTri(x,y,z)
DT = DelaunayTri(..., C)
Description
DT = DelaunayTri() creates an empty Delaunay
triangulation.
DT = DelaunayTri(X), DT = DelaunayTri(x,y)
and DT
= DelaunayTri(x,y,z) create a Delaunay triangulation from a
set of points. The points can be specified as an
mpts-by-ndim matrix X,
where mpts is the number of points and ndim is the
dimension of the space where the points reside, where ndim is 2 or 3.
Alternatively, the points can be specified as column vectors (x,y) or
(x,y,z) for 2-D and 3-D input.
DT = DelaunayTri(..., C) creates a constrained Delaunay
triangulation. The edge constraints C are defined by an
numc-by-2 matrix, numc being the number of
constrained edges. Each row of C defines a constrained edge in terms
of its endpoint indices into the point set X. This feature is only
supported for 2-D triangulations.
Examples
Compute the Delaunay triangulation of twenty random points located within a unit square.
x = rand(20,1); y = rand(20,1); dt = DelaunayTri(x,y) triplot(dt);
