<viewpoint>.link
Hi,
I tried using the link function for a viewpoint doing what is in the help (something like: myview.link(mysensor)) but I get a error message stating that link() requires 3 arguments (2 given). What is the 3rd argument? David Last edited by david; 12-12-2003 at 01:24 AM. |

Hi David,
Just pass in 0 as the second argument. In the current version you don't need to do this, you might have an older version. |

need more explanations
Thanks for your answer Farshizzo but I still don't understand.
I ran the following lines: headTrack = viz.addsensor('is600') #is600 is a custom plug-in that can track two sensors headView = viz.add(viz.VIEWPOINT) headView.link(headTrack,0) And I got the error Traceback (most recent call last): File "<string>", line 2, in ? File "test_attach_other_viewpoint.py", line 13, in ? headView.link(headTrack,0) File "C:\Program Files\Vizard20\viz.py", line 1354, in link _ipcSend(_VIZ_LINKVIEW,self.id,sensor,id,'',mask,0 ,0,0) TypeError: function takes exactly 8 arguments (9 given) Then I tried putting the mask argument (0) first and tried the following script. But apparently the HEAD_LOOK vector is not updating, and I only get the vectors [0,0,1,0] over and over again. import viz viz.go() headTrack = viz.addsensor('is600') headTrack.command(11) # Uses only 3 dof to prevent drifting of the scene # To switch back to 6 dof use command(1) handTrack = viz.addsensor('is600') handTrack.command(11) headView = viz.add(viz.VIEWPOINT) headView.link(0,headTrack) handView = viz.add(viz.VIEWPOINT) handView.link(0,handTrack) def test(t): vect = headView.get(viz.HEAD_LOOK) print 'headLook',vect vect = handView.get(viz.HEAD_LOOK) print 'handLook',vect viz.starttimer(0,3) viz.starttimer(0) viz.callback(viz.TIMER_EVENT,'test') |

Hi David,
Thanks for including the error message, there is a typo in viz.py. The following line: Code:
_ipcSend(_VIZ_LINKVIEW,self.id,sensor,id,'',mask,0,0,0) Code:
_ipcSend(_VIZ_LINKVIEW,self.id,sensor.id,'',mask,0,0,0) |

It seems to be working. Thanks!
I still have to test with the sensors connected, but it should work. At least I do not get a compilation error David |
