As Joerg and I stated, there is no reason to use two TransformGroups. Using separate TransformGroups only wastes memory and performance.
Perhaps you aren't understanding what a tranform does. The rotation has nothing to do with the positioning (i.e. rotating it doesn't move it in a different direction it just changes the object's orientation). I think you'll find it easier if you keep the position, speed and orientation in separate variables (don't fetch them from the transform!) and just use basic geometry to calculate the new position and orientation and then apply it using the TransformGroup. - John Wright Starfire Research Jaakko Holopainen wrote:
