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...

alleged to the video 'tutorial' "the Mechanics and its Simulation". Simulation with Lagrangian method, both symbolic, and by numerical derivation. All well-grouped in folders. there is also a 'review' in 3 demos of the Newtonian dynamics: mass-spring systems. most of progs are written in C, with use of SDL lib to display simple graphics and have real-time interactivity. As to programming complexity, it's very simple... this all aims at classical physics simulation in a simple but efficient way...

2D simulation game using exlusively Lagrangian equations of motion. It's a 2D motocross game similar to X-Moto, ActionSupercross and such. Some stability issues persist but mostly it's good already. I shall compile it soon for Windows: one of the problems is that Windows compilers must periodically be reinstalled, and that's annoying. Using Lagrangians in games is not a well documented thing, but it allows to achieve exellent results in very little time, soon after a good parametrization...

CTruck 2D is a 2D, oldstyle, physically realistic 2D truck game. Predecessor of the CTruck3D vehicle simulator series. I wrote it from zero in C (+OpenGL&GLUT). It has ascii-art and nice graphics version, and a special funny version It's a very basic thing: there are free rigid bodies and springs with strong attenuation/damping. It's very simple and very short code, and collisions of bodies with ground are good and stable. A good simulation of this kind, however requires Lagrangian...
