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.
