calculate the volume of a patch object

I have a patch object (enclosing a 3d volume), containing, faces, vertices, Xdata, Ydata and Zdata. May I ask how I can calculate the volume of this object. Thank you very much!

Any updates, @Jason? Did you try any of the methods posted below?

Answer 1

[Dyuman Joshi]

You can use convhulln which returns the volume of the convex hull as the 2nd output.

Perhaps first using alphaShape and then volume will do what you want.
