Hello,

How to calculate the volume of these 3D models using vertices and faces and edges?

Thanks.

You need depth information to get the volume and that is missing in your images. There is no way to do what you ask as things stand.

Hi!

You can calculate the volume if you create a 3d mesh (e.g. with tetrahedrons) of the models. But this is not trivial!

If you have this you just sum up the volumes of all tetrahedrons. This is easily done using

V = 1/6 * dot(a, cross(b,c));
