Volume from 3d point

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

You'll get the volume of the convex hull by

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

Thanks Bruno. How do I get volume by concave hull?

[Bruno Luong]

A volume is defined by (thetrahedron) connectivity, in addition to a list of scattered points. In your case you just gives the list of points as input, so the volume is not defined. The only one that is defined is by default the convex hull.
