about Kinect coordinate transformation

Code:
import viz
import vizshape

viz.go()
grid = vizshape.addGrid()

"""
Kinect Tracker object ID's
These are not actually being using in the script but are to
help anyone who wants to get access to a specific bodypart.
For example to just get a handle to tracking data for the head use:
myHead = vrpn.addTracker( 'Tracker0@localhost', HEAD).
"""
HEAD = 0
NECK = 1
TORSO = 2
WAIST = 3
LEFTCOLLOR = 4
LEFTSHOULDER = 5
LEFTELBOW = 6
LEFTWRIST = 7
LEFTHAND = 8
LEFTFINGERTIP = 9
RIGHTCOLLAR = 10
RIGHTSHOULDER = 11
RIGHTELBOW = 12
RIGHTWRIST = 13
RIGHTHAND = 14
RIGHTFINGERTIP = 15
LEFTHIP = 16
LEFTKNEE = 17
LEFTANGLE = 18
LEFTFOOT = 19
RIGHTHIP = 20
RIGHTKNEE = 21
RIGHTANKLE = 22
RIGHTFOOT = 23

#store trackers, links, and vizshape objects
trackers = []
links = []
shapes = []

#start vrpn 
vrpn = viz.addExtension('vrpn7.dle')

#now add all trackers and link a shape to it
for i in range(0, 24):
    t = vrpn.addTracker( 'Tracker0@localhost',i )
    s = vizshape.addSphere(radius=.1)
    l = viz.link(t,s)
    trackers.append(t)
    links.append(l)
    shapes.append(s)
The code above can be used to track human skeletal.

Is there a way to convert the tracking white dots always shown in front of the mainview (maybe 1 or 2 meter distance from the mainview), when the mainview changed, the white dot will also follow the mainview to change to another position.

It should be something regarding coordinate transformation.

Thanks,
