Hi,

I would like to simulate, for a starter, objects that rotate around an axis. Trigger them to start at a specific speed, simulate friction that progressively reduce frequency, and also bias them with weights to make uneven rotation. (I will use this to drive synthesis in Pd).

I have seen that there are some libraries on the theme, like pmpd,

What would be a good starting point for exploring this?

The purpose is to control sound, a visual representation would be nice but is not necessary.

Thanks!

@cfry pmpd has many examples in pmpd/examples..... some with sound already.
The Gem/examples/06.particles has some physical modelling as well.
Some Gem pix_ objects output control rate data about the image that you could use for audio generation..

I think you are refering to the pmpd library included into PD-Extended.

This could also be used to controle position of the objects, by affecting, among others parameters, pan and volume.

Like I did in this abstraction but with even more possibilities.
