I have some source code where I use a trackballmanipulator to rotate a terrain. If I drag the mouse I can set the terrain spinning. How do I programatically stop this (i.e., without clicking the mouse again)? I tried setting Manipulator->setRotation(last_saved_angles), which does reset it , but it looks like the previous dragging motion queues up lots of mouse events that then continue to rotate the terrain on subsequent render loops.
