The skeletal appears in front of the mainview but I wish to obtain the position of the skeletal joints in global coordinate.

When I apply "pos_s = s.getPosition() print pos_s" to the code, it seems the position is still their local position, is there a method using coordinate transformation to achieve keeping skeletal appearing in front of the mainview.

waiting for the reply
