#X text 30 25 The aim of this collection of objects is to create physical
behavior with pure data. It's not audio synthesis. But it can be used
for the creation of parameters that can be used for driving an audio
or video synthesis.;
#X text 30 101 Most of the examples use GEM \, to allow visualization
of the "physical" geometry \, but you don't need it to use this collection.

#X text 30 161 any comments \, criticism \, suggestions \, help would
be highly apreciated :;

#X text 34 30 Object in this collection can be mass \, link and interactor
\, in 1D \, 2D or 3D.;
#X text 47 69 Masses (mass \, mass2D \, mass3D) are ponctual. They've
got a weight \, and know their position. They can move when they receive
a force \, acording to physical rules.;
#X text 47 126 Link (link \, link2D \, link3D) are the basic interaction
beetween 2 masses. It is a visco-elastic link. The link object receive
the position of 2 masses \, compute the force beetween the 2 masses
and output a force for each mass.;
#X text 47 202 Interactors are a kind of link \, but influence a group
of masses at once. They can be used for global interaction. We will
look further into it later.;
#X text 32 272 This collection of objects can be interconnected for
the creation of "physical" structures. Such structures can then move
\, and distord themselves \, according to forces applied to them.;
#X text 29 350 The resulting movements are very natural \, due to the
physical equations used to define the objects.;
#X text 30 418 all objects can be created using pmpd.name \, instead
of name in order to avoid name conflict between libraries.;
#X text 29 466 ex :;

#X text 36 452 Here is the basic connection beetween 2 masses :;
#X obj 40 591 lia;
#X text 36 529 You can also create things like this :;
#X text 32 23 For patching simplification \, objects in this collection
only have "cold" inlets. The computation speed depends on an external
metronome. This metronome should bang alternatively all links in the
model and then masses of the model.;
#X text 33 103 mass and link have a name corresponding to their class
name. They will receive everything sent to this name.;
#X text 159 236 clicking on bang 1 or 2 is equivalent;
#X text 32 304 As you sould send a bang alternatively to links and
masses \, you sould give diferent names to the links group and masses
group.;
#X text 36 361 Masses output their position when you bang them. This
position depends on the forces applied to the mass.;
#X text 36 401 Links output a force according to the position of the
masses when you bang them. This force sould be applied to the same
mass.;
#X text 40 626 The masse1 will never receive forces \, so it will never
move. It is useful for creating a structure attached to a fixed point.
