origin position=[0,0,0] turn axis,angle can change the origin, but x,y,z are always in the camera frame of reference with the turn and move commmands. > Reason for asking this is that it would be very nice (at > least for me) to be able to perform "local" transformations > (i.e. about local object axes, be it the camera or other) > that are bound to locally-defined axes > - that are independent of the "global" or viewport orientation. For this, use the rotate command. # atomic coordinate based (geometry must be recomputed) rotate x,90, # object matrix based (geometry remains valid, but causes other problems) rotate x,90,object=object-name Note that the optional "camera" option (0,1) can control whether global or camera frame of reference applies, and that the current global origin is always the center. origin object-name-or-selection to change it Don't mix the two types of rotations or PyMOL will get confused.
