MATLAB: Volume from 3d point

Question

Hi there,

I am trying to calculate the volume of a stockpile using 3d points gathered.

First I created three matrices. X, Y and Z

Here's the simple code used

tri = delaunay(X,Y,Z);

h = trisurf(tri, X, Y, Z);

Now I'm stuck on calculating volume. Could you kindly assist.

Thanks

Answer 1

You'll get the volume of the convex hull by

[~,V] = convhull(X,Y,Z)
