problem starting/stopping auto tracking - WorldViz User Forum

hotspur1 · #1 11-14-2003, 01:13 PM

The documentation says that I can start and stop the automatic tracking using the following notation

viz.tracker(viz.START) or viz.tracker(viz.STOP)

Unfortunately for me, this doesn't work.
I have an IS-600 and am using the intersense.dls plug-in provided with Vizard version 2.12 (patched version for the callback problem). I initialize the tracker as usual with

trk = viz.add('intersense.dls')

Does this feature work yet? Is there a workaround? I would like to do an experiment comaring head tracking on or off, so to be able to switch on the fly would be most useful.

Hi,

You're right, this feature has not been implemented yet. There is a workaround. To stop tracking perform the following:

Code:

viz.get(viz.MAIN_VIEWPOINT).unlink(0)

This will be fixed in the next version though.

Great - but to start the tracking again, do I just issue the viz.tracker() command again?

Yeah, issuing the tracker command should work again. Thanks for pointing out this problem.
