I am kinda confused with box function to create a rigidobject box to the environment
def box(width,depth,height,center=None,R=None,t=None,world=None,name=None,mass=float('inf'),type='TriangleMesh')
First, I am not sure what's the difference between center and t. They both seems to be some locations. From my test, only center can be used to specify object's initial position and t cannot.
The second question is how to get this box's position in world coordinate. I use box.getTransform() and it seems that it is returning some offset w.r.t. its initial position, not the actual position in the world.
I guess the correct way is to not specify center, but use setTransform() to initialize box position?
