moving locally

Hi dear all
I have some problems to move an object with 'REL_LOCAL' property.
I have linked as follows:
mylink = viz.link(viz.MainView , hand)
mylink.setDstFlag(viz.LINK_POS_RAW)
mylink.preTrans([0,-.15,0])
mylink.setMask(viz.LINK_POS)

I just need Position of 'hand' object, links to mainview position. but I want to move 'hand' object relative to its local coordination. I have (X,Y,Z) to move locally. in fact (X,Y,Z) are local coordination like (1,0,1) not global coordination.

May help me to how can I do this?

The example below links the hand to a keyboard tracker and keeps it in the reference frame of the main view:

Code:

import viz

viz.go()



import vizinfo

vizinfo.add("To move the hand use 'a/d' left/right, 'w/s' forward/back, 'r/f' up/down")



import viztracker

keyTracker = viztracker.KeyboardPos()



hand = viz.addAvatar('hand.cfg')

ground = viz.addChild('tut_ground.wrl')



link = viz.link(keyTracker,hand)

link.preTrans([0.2,0,1])

link.postMultLinkable(viz.MainView)
