Rigid body parameters of closed surface meshes软件

Fast computation of exact rigid body parameters of closed triangular surface meshes using divergence theorem

软件应用简介

In order to simulate dynamic behaviour of a rigid-body, one requires knowledge of a set of rigid-body parameters such as the total mass of the rigid-body, the center of mass, as well as the moments and products of inertia. The purpose of this submission is to provide a function that can compute exact rigid-body parameters of objects represented by closed, triangular surface meshes. The principles underlying all computations are based on the divergence theorem and are explained in detail in the attached document.

This submission also includes two functions that take as input an arbitrary mesh and output parameters of a primitive object, such as an ellipsoid or a cuboid, with exactly the same inertial parameters as the input object.
