whch is the best free software like meshlab which can be used for moment of inertia calculation of collada file except meshlab? Currentely my computer only has ubuntu in it. I installed the meshlab 1.3.3 but it do not have filter option to calculate moment of inertia of a collada file. I try to install meshlab 1.2 from source but i have problem in doing so. All the robot links are not symetrical.
