id	Name	DataType	PartType	Default	ValueType	Description
	collisionDomainParam	MFFloat	inputOutput			parameters like center and radius for creating collision objects, last param [>]0 means [dis]connected
	springConstant	MFFloat	inputOutput			spring constants/ damping for springIndex field
	anchorIndex	MFInt32	inputOutput			contains all points which are not allowed to move
	index	MFInt32	inputOutput			index field, holds topological information of mesh, used to create springs
	springIndex	MFInt32	inputOutput			user defined springs, e.g. [3 7 -1 2 9 -1]
	collisionDomainType	MFString	inputOutput		[NONE, SPHERE, PLANE, BOX, ELLIPSOID, CYLINDER]	type of collision object, e.g. plane or sphere, each object has up to nine params. NONE: no object; SPHERE: spherical object; PLANE: planar object; BOX: box shaped object; ELLIPSOID: ellipsoidal object; CYLINDER: cylindrical object;
	logFeature	MFString	inputOutput		state, child, parent, route, eventIn, eventOut	controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
	springTypes	MFString	inputOutput		[STRUCTURAL, SHEAR, BEND]	Used for automatic spring generation. STRUCTURAL: connects along edge; SHEAR: connects along along diameter; BEND: connects mass with the mass two edges further;
	coord	MFVec3f	inputOutput			coordinates of vertices resp. mass points (updated during simulation)
	normal	MFVec3f	inputOutput			vertex normals
	velocity	MFVec3f	inputOutput			initial velocity
	autoCalcAnchor	SFBool	inputOutput	TRUE		if true, collect all indices of points being inside collision objects
	enabled	SFBool	inputOutput	TRUE		Flag to enable/disable the node behaviour
	individualDistance	SFBool	inputOutput	FALSE		use offset distance to collision objects to avoid penetration
	isActive	SFBool	inputOnly			enable/ disable picking of mass points
	localCoordSystem	SFBool	inputOutput	TRUE		evaluate calculations (e.g. gravitation) in local or global coordinate frame
	airFriction	SFFloat	inputOutput	1.0		generic damping factor for simulationg viscosity of air
	bendDamping	SFFloat	inputOutput	0.6		bend spring-damper-element
	damping	SFFloat	inputOutput	0.1		viscous drag coefficient (world)
	mass	SFFloat	inputOutput	1		the mass (assumed the same for all mass points)

	perMassRandomPerturbation	SFFloat	inputOutput	0		perturb wind etc. per mass
	restitution	SFFloat	inputOutput	0.1		coefficient of restitution (says how much object is bouncing back)
	shearDamping	SFFloat	inputOutput	0.6		shear spring-damper-element
	slidingFriction	SFFloat	inputOutput	0.2		friction occuring during fast motion
	speed	SFFloat	inputOutput	1		Scaling factor for simulation speed.
	springConstantBend	SFFloat	inputOutput	4		hook's spring constant (for bend type)
	springConstantShear	SFFloat	inputOutput	4		hook's spring constant (for shear type)
	springConstantStructural	SFFloat	inputOutput	4		hook's spring constant (for structural type)
	springConstantUser	SFFloat	inputOutput	1		user spring constant (needed for e.g. dragging)
