trimesh: Display triangles mesh (2D)

In geometry: Mesh Generation and Surface Tesselation

Description

trimesh(T, p) displays the triangles defined in the m-by-3 matrix T and points p as a mesh. Each row of T specifies a triangle by giving the 3 indices of its points in X.

Usage

trimesh(T, p, p2, add = FALSE, axis = FALSE, boxed = FALSE, ...)

Arguments

T	T is a m-by-3 matrix. A row of T contains indices into X of the vertices of a triangle. T is usually the output of delaunayn.
p	A vector or a matrix.
p2	if p is not a matrix p and p2 are bind to a matrix with cbind.
add	Add to existing plot in current active device?
axis	Draw axes?
boxed	Plot box?
...	Parameters to the rendering device. See the rgl package.

Examples

#example trimesh
p = cbind(x=rnorm(30), y=rnorm(30))
tt = delaunayn(p)
trimesh(tt,p)

Example output

     PLEASE NOTE:  As of version 0.3-5, no degenerate (zero area) 
     regions are returned with the "Qt" option since the R 
     code removes them from the triangulation. 
     See help("delaunayn").
