Rigid body physics (machine learning environment)

SUMMARY

This discussion focuses on simulating the rotation and balance of mesh characters in a machine learning environment. The key challenge is determining how fast a mesh character will rotate and fall based on its center of mass. The conversation highlights the importance of analyzing the mesh's vertices and their contact points with the ground to maintain balance. Additionally, the simulation's accuracy will depend on the equations used for gravity and the time intervals for mesh adjustments.

TL;DR
how would I simulate rotation on a mesh character when there is nothing to hold it's center of mass.
I guess that the reason that objects fall over is that there is nothing to hold it's center of mass. So what I want to do is to work out how fast in Delta intervals it would rotate and fall over.

Welcome to PF. :smile:

What's a mesh character? Is this for a computer simulation of a person for CGI?

What kind of simulation software do you have available for these simulations? Or do you mean just simulating motion of a 3D object using equations (and some simple plotting software like Excel)?
 
This is for use in a machine learning environment where a mesh will have to learn to walk around and keep it's balance. So like my post says I will get the center of mass and check it's vertices and see if there is a part touching the ground on 4 sides past it's center of mass. Changes to the mesh will happen in timeframes. So I guess this will be dependent on things like my equation for gravity?
