geoConnector

Go to: Related nodes. Attributes.

The geoConnector node provides an interface between ordinary geometry objects (such as NURBS surfaces) and the dynamics system. A geoConnector node is associated with any such geometry which is emitting particles, exerting a force field, or colliding with particles. The geoConnector node is not used when making an object a rigid or soft body. The node stores positions (and if necessary, pseodo-velocities) for the geometry, and provides a tesselated polygonal representation if needed for emission or collisions.

The most recent time at which position/velocity data was computed.
deltaTime (dlt)	time	0film
time difference between aCurrentTime and aPrevTime.
owner (own)	Message	n/a
Message connection to owning geometry shape. Necessary to support curve on surface. Users should not modify.
inputGeometryMsg (igm)	Message	n/a
Obsolete. Retained for file load compatibility in 2.0. Will be removed for 3.0.
localGeometry (lge)	Generic	n/a
Used to obtain local surface/curve data from associated geometry.
worldMatrix (wm)	matrix	identity
It is the global transformation matrix which is used to transform CVs to the world space.
ownerPositions (pos)	vectorArray	empty
All edit point positions of the owner shape.
preOwnerPositions (pop)	vectorArray	empty
All edit point positions of the owner shape when last computed. It is used to compute owner's edit point velocities.
ownerVelocities (vel)	vectorArray	empty
All edit point velocities of the owner shape.
ownerMasses (mas)	doubleArray	empty
Currently this always returns null. It is provided for possible future expansion to return an array of owner masses.
idMapping (idm)	compound	n/a
Currently this attribute is not used by the geoConnector. It is provided for possible future expansion. When springs are placed on geometry, an input connection to this attribute is made. But the geoConnector currently never requests the input.
sortedId (sid) intArray empty Currently this attribute is not used by the geoConnector. It is provided for possible future expansion. When springs are placed on geometry, an input connection to this attribute is made. But the geoConnector currently never requests the input.
idIndex (idix) intArray empty Currently this attribute is not used by the geoConnector. It is provided for possible future expansion. When springs are placed on geometry, an input connection to this attribute is made. But the geoConnector currently never requests the input.
inputForce (ifc)	vectorArray	empty
Currently this attribute is not used by the geoConnector. It is provided for possible future expansion. When springs are placed on geometry, an input connection to this attribute is made. But the geoConnector currently never requests the input.
