Electric Field Force-Based Detection of Rotational Symmetry in 3D Model

In this paper, we propose a method to describe the rotational symmetry in 3D shapes. This symmetry is deterministically found through the use of a physical quantity: electric field force. He describes the measure of the shape´s rotational symmetry with respect to every axis passing through the center mass. This algorithm can deal with complex and ill-defined models because of its physical background. 3D model supposed as charged body, we get the electric field force distribution by placing some testing charges on the big circle of the 3D model, and then get the rotational symmetry by calculating the difference of the electric field force.
