Only if you have all coords in the same units, model and screen parameters. Most models are in meters, the OSG defaults are all in meters so if you want things to work out the box it's best to stick to meters otherwise if you miss one parameter you can get a mixture of units. > So the question remains.

The trackball manipulator tells the viewer to scale the interoccular distance by the distance between the eye point and the center of rotation of the trackball. This mode allows you to view molecules up to planets without having to dynamically manage the interoccular distance yourself. The FusionDistance is the name given to the distance between the eye point and center of rotation/pont at which the left and right eye views overlap (which is the image plane of the display system), in hindsight parallax distance would have been a better name...
