Hi Dennis, For a pure physics sim I wouldn't have thought you'd need any viewer at all. You'd just need to use a UpdateVisitor and your own updating of the FrameStamp to signal the new frames. You will need to the updates from the physics to update the scene graph, I'm not familiar with osgNV+PhysX combination so can't comment how this would be done, or what is already provided for you. One would typically implement a pull mechanism from the scene graph where an update callback gets the data from the physics simulation, or a push mechanism where once per frame you apply all the data from the physics simulation to the scene graph in one go.
