A simple bi-directional two-mass model that can serve as a hammer, plectrum, finger, etc. Generally the two-mass model has a small mass and a large mass; the small one will be "connected" to the object being excited, and the large one will be manipulated by the user. This is similar to the bi-two-mass, except that it only vibrates in the trans0 direction. It is therefore more computationally efficient for single-direction interactions like plucking and striking objects.
A 'mono-two-mass can be created using the following Lisp syntax (the default values are shown for each of the physical parameters):
All physical parameters can be numerical values or controllers.
As always, the term horizontal used above is provided for simplification.
A 'bi-two-mass can be accessed only in its sole vibrational direction: trans0.
(make-access my-mono-two-mass my-controller 'trans0)
If the value of my-controller is 1, the access is on the small mass. If my-controller is 0, the access is on the large mass. (A value in-between takes a weighted combination of the two points.)
There are no special options for the mono-two-mass.
