lagrangian dynamics nf sims

We have hosted the application lagrangian dynamics nf sims in order to run this application in our online workstations with Wine or directly.

Quick description about lagrangian dynamics nf sims:

Articulated-body simulation engine written in C: based on the Lagrangian Dynamics, even if on a modified flavour of it, I deviced to make it more friendly in the context of numerical simulations.
The overall simulation procedure (de facto a full 3D, an articulated-body simulaiton engine) is called:
"Lagrangian Dynamics' New Flavour Simulations".

It is delivered through sample-simulators relying on it.

The modified falvour of the Lagrangian Dynamics here proposed is also a bit simpler to use and to understand than the original one. Of course it is all based on finite-differece derivatives, both oridinary and partial.
The new flavour relies on my first theorem on Numerical Methods,and the 1 on numerical stability

Hope this piece of software will be useful to many. For more info,visit homepage. I will provide detailed documentation on how to use the engine to implment simulations of most types of articulated bodies, soon.

Enjoy!

Features:

• In the "Files" section, the individual examples can be downloaded.
• very short and simple sourcecode, written in plain C programming language
• progressively expanding, massive and clear documentation
• Use of the Lagrangian Dynamics in a modified flavour of it, which, however preserves all of it's strong points ; while eliminates all of it's drawbacks
• use of generalized coordinates instead of independent bodies kept togather by constraint-forces excerted by joint-mechanisms. There, at che centre of the view is the mechanism as a whole, which, at each instant, has a configuration.
• most documentation is in video-form, which then shall be transcribed: so it's more funny
• many examples, many of which are also funny as stand-alone simulation-videogames.
• in-build support for basic free-roaming vehicle simulation.
• the author welcomes questions and requests about the simulator, and so is active in helping to create a very solid and friendly documentations and kit of functioning examples
• I recently updated some examples in which there was a little mistake: now it's fine.

Audience: Developers, End Users/Desktop, Engineering.
User interface: OpenGL, Project is a 3D engine, SDL.
