Hello,

Thanks for the reply and the examples and thanks to the really well designed pmpd, it is easy to find a working simulation and can be solved and visualized in different ways and the three body problem is a classic task for that. So I guessed that some, from the pd patch family, were looking for and found a solution to create music and sound art.

Of course, the three-body system is only stable for a small range of initial conditions and is not mathematically solvable.

The solution Benjamin sent me is really cool: Simulation in the signal domain and visualization with scope and audio rendering in the ambisonics domain, which was the initial motivation for it.

So thanks Benjamin for the solution and artwork and Henry for the wonderful library.

Hello Winfried,

It's really easy to simulate this problem. Benjamin Wesch send me a patch off list. I added it to mine, so here are 4 different way to go. (using mass2d, pmpd2d, pmpd2d~ and pmpd3d~)

The biggest challenge is finding initial conditions that did not result in a very fast divergence of the masses.

cheers C

PS.:just curious... wanted it for a demonstration.
