trimesh

Triangular mesh plot

Syntax

trimesh(Tri,X,Y,Z,C)
trimesh(Tri,X,Y,Z)
trimesh(Tri,X,Y)
trimesh(TR)
trimesh(...'PropertyName',PropertyValue...)
h = trimesh(...)

Description

trimesh(Tri,X,Y,Z,C) displays triangles defined in the m-by-3 face matrix Tri as a mesh. Each row of Tri defines a single triangular face by indexing into the vectors or matrices that contain the X, Y, and Z vertices. The edge color is defined by the vector C.

trimesh(Tri,X,Y,Z) uses C = Z so color is proportional to surface height.

trimesh(Tri,X,Y) displays the triangles in a 2-D plot.

trimesh(TR) displays the triangles in a triangulation representation.

trimesh(...'PropertyName',PropertyValue...) specifies additional patch property names and values for the patch graphics object created by the function.

h = trimesh(...) returns a handle to the displayed triangles.

Create Triangular Mesh Plot

Create vertex vectors and a face matrix, and then create a triangular mesh plot.

[x,y] = meshgrid(1:15,1:15);
tri = delaunay(x,y);
z = peaks(15);
trimesh(tri,x,y,z)

If the surface is already a triangulation representation, then you can pass the triangulation to trimesh:

tr = triangulation(tri,x(:),y(:),z(:));
trimesh(tr)
