Mismatched Translation Between Real Motion and Display
I’m using Optotrak to capture motion to update the visual scene accordingly. However, I can’t get the scene to react properly to the marker motion. Below is how the first-person view in the scene changes when moving I move with the marker.
When we rotate left and right, the scene updates how we want. But as shown above, the 4 translations do not update the scene correctly. I performed my Optotrak alignment to match the XYZ coordinates of the pit.osgb model that Vizard provides, but the real-life motion still doesn’t update the visual scene correctly. Am I approaching this wrong? Is there something I need to add to the script regarding the coordinate system? Thanks! |

It should not be necessary to make any modifications to the coordinate system in Vizard. Try testing with the following script after specifying the correct hostname:
Code:
import viz viz.go() viz.addChild('piazza.osgb') opto = viz.add('optotrak.dle',0,'192.168.0.114') body = opto.getBody(0) viz.link(body,viz.MainView) |

I repositioned the cameras while using the default Optotrak alignment and it now tracks properly.
Thanks! |
