Hi Nathan, The fusion distance is either user set, in the case of Drive and FlightManipulators, or calculated per frame in the case of Trackball and TerrainManipualtors. The later two manipualtos set the fusion distance as the distance between the eye point and the center of the rotation of the tracbball - it is not related to the near/far planes.
