Vizlink problem

[pattie]

Below is a sample piece of code (numbered lines for clarity) that I play around with in order to make sure I understand the linking process.
1: import viz
2: viz.go()
3: block = viz.add('box.wrl')
4: block.translate(0,1.8,3)
5: marker = viz.add('marker.wrl')
6: marker.scale(0.1,0.1,0.1)
7: marker.translate(0,1.8,0)
8: link = viz.link(marker,block)
9: print "marker pos is: ", marker.getPosition()
10: print "block pos is: ", block.getPosition()
11: marker.translate(0,11,24)
12: print "marker pos is, after translation: ", marker.getPosition()
13: print "block pos is, after translation: ", block.getPosition()
14: link.remove()
15: marker.translate(0,1.8,41)
16: print "marker pos is, after remove: ", marker.getPosition()
17: print "block pos is, after remove: ", block.getPosition()

If I run this program, I notice that the block position (line 13), (the node being linked to the marker on line 8) is is not updated after the marker is translated (line11). I do not understand why. Shouldn't the block position be applied the translation too?

Furthermore, If I understand correctly, the remove() function is like an unlink command. Is that correct?

Thanks for your reply
