trimesh (MATLAB Function Reference)

Triangular mesh plot

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

Description

trimesh(Tri,X,Y,Z)

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.

trimesh(Tri,X,Y,Z,C)

specifies color defined by C in the same manner as the surf function. MATLAB performs a linear transformation on this data to obtain colors from the current colormap.

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 a Patch graphics object.

Example

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

x = rand(1,50);
y = rand(1,50);
z = peaks(6*x-3,6*x-3);
tri = delaunay(x,y);
trimesh(tri,x,y,z)
