Multiply all the transforms of the transform groups. From the resulting transform you can extract only the translation component.

But there should certainly be a mathematical method to calculate all the translation matrices for a given collection of TransformGroup so that we could Translate the collection to a desired point in 3d Space My question has not been answered yet i just want a method to calculate all translation Matrices (Or one Matrix , what ever) that could be applied to the collection of TGs so that i m able to Translate the collection to a desired point without changing the orientation of any TG relative to any other TG in the Group Pointers Please!!
