Hello everyone,
I have 3d center coordinates and radii of an object which is made up of poly-disperse spheres (as shown in the figure). I want to compute the total volume of the object by using convhulln, please guide me the right way to do it. I want to include the input of 3D center coordinates and radii as well in order to get the total volume of the object. (I have done it by simply giving center coordinates as input the volume value came out as very small)

The object shown in your diagram is not convex. You might get a better result using an alphaShape instead of a convex hull.

Thankyou Steven, I will try alphaShape. My study requires comparison of volume by different methods. DO you have any idea how can I compute the total volume of same object by dilation(ball3)?
