Lagrange Rally 3D
3D vehicle simulator based on Lagrangian dynamics to simulate dynamics
3D vehicle simulator in which vechicle's configuration as a whole (articulated body) , is represented by a 'vector' of generalised coordinates. so concepts like usual position and orientation of main body and wheels is all defined by the generalised coordinates.Using Lagrangian dynamics, theese coordinates are evolving in time in a realistic manner according to F=ma but as if there were also all constraint forces concretasing the presence of joints: hinge, prismatic, rigid connection, etc. all derivatives are done with finite differences, so it's all simple. in 3 videos I explain all the mechanics and its simulation up to this simple but pow method.Pure Lagrangian mechanics until now has not been used much or at all,in simulation videogames,but i decided to try it because it was promising, very simple compared to the fnal results, and there was not much docu on its use in simulation games: this lack was completed now.
will com also a non-GL version
