recieve all data from tf message
listener.lookupTransform('/frame1', '/frame2', rospy.Time(0))
function works with 2 frames, so if i need to know all frames positions, relative to frame1, i have to call "lookupTransform" for each frame? Is that right way?
I mean, if i have 10 frames, i should call lookupTransform 9 times, is this normal to performance?
