How to create marching triangulation or advance front mesh in Matlab ??

I have used delauney triangulation method in a grid (which created ortho trias)

I would like to know how to create marching trias/advancing trias ?

This is the code created for a small mesh grid

It creates two figures one with triangular mesh another with just grid points.

How to create marching trias for figure (2)

clc

close all

[X,Y]= meshgrid(1:11);

figure; hold on;

plot(X,Y,'k');

plot(Y,X,'k');axis off

grid on

tri = delaunay(X,Y);

   figure(1)

   trimesh(tri,X,Y)

figure(2)

plot(X,Y,'.')

Thanks

It looks cool ! lemme have a check.

gone through it ,most seems to be for structured applications. It's there for unstruc too ,but the grid need to be unstruc for the process to follow.

That code generates unstructured mesh.
