Plotting Triangulations

MATLAB provides standalone functions to plot triangulation representations. These functions can take 2- and 3-D TriRep and DelaunayTri objects as input.

Create a 2-D Delaunay triangulation and plot it with triplot:

x=rand(10,1);
y=rand(10,1);
dt = DelaunayTri(x,y);
triplot(dt)
hold on;

Plot the Voronoi diagram with voronoi:

voronoi(dt)
hold off;

You can also plot 3-D triangulation representations.

load tetmesh
TR = TriRep(tet, X);
tetramesh(tet,X,'FaceColor','cyan')

You can plot a surface mesh with trisurf.

load trimesh3d
TR = TriRep(tri,x,y,z);
trisurf(TR)
