Hello, 

This is really not my area so this may be a stupid question. I'm wondering if there are known algorithms for modelling the behaviour of physical material. For instance, disturbances on the surface of water, or elasticity, or entropy. I'm sure there are but has any such thing found its way into csound or another music software?

For instance, I would like to set up some perpetual sonic activity that is deformed by an intervening force (coming from sensors), leaving some sort of decaying aftermath, like ripple on the water. Not sure if that conveys the message but at least I tried!

Thanks in advance

You could perhaps use scanned synthesis for something? It is essentially a large mass-spring system (correct me if I'm wrong). You can input energy to the system by using the hammer opcodes, audio input,  or simply writing to the scanned table.  Then read your values 'manually' from the scan table instead of using the scanning opcodes.

Hello, 

Thanks for all the pointers everyone. I'm following up the links. 

Oeyvind, that's interesting. I'll try it tonight. I'm getting the audio signal from the arm muscles with one of these, which could work well as an exciter.

Looks promising! Great idea to connect the Xth sense to it.
Perhaps this is also relevant:

I saw the presentation in York last year. You may already know of course(?)
