mov3 (xa = val 1 , ya = val 2 , za = val 3 ) aim3 (xa = val 1 , ya = val 2 , za = val 3 ) setz3 (zc = dist)
mov3 moves the current 3D plot by val 1 along the viewer's x axis, val 2 along the viewer's y axis,
and val 3 along the viewer's z axis. aim3 moves the current 3D plot to put the point (val 1 , val 2 ,
val 3 ) in object coordinates at the point (0, 0, 0)--the aim point--in the viewer's coordinates. In both
functions, if any of the val 1 , val 2 , or val 3 is missing, it defaults to 0.
setz3 sets the camera position to dist (x = y = 0) in the viewer's coordinate system. If dist is
None or if zc is missing, set the camera to infinity (default).
