coordinates
 

I have a question regarding coordinates. When you run a scene let's say I ran lab.wrl that's in the resource. When you run the program , are we at position 0,0,0? Where about are we located? What about when we connect to Optotrak? How do we know the coordinates of our starting point?

If you're using the default mouse navigation to control the viewpoint, the starting position is [0,1.8,0]. If the viewpoint is controlled by tracking data and there are no other offsets applied, the starting location should be the position returned by the tracking device.

Thank you very much for your reply. How can we return the starting position if we are using Optotrak?
