Vector Calculation

Hello,
I am trying to develope a small tracking application.
In this application I need to track all head postions (6DOF) along with hand movments.
For tracking the hand I am using several dots, which in my application I calculate their positions.
To track the head I am using the Vector track with a specific camera - which works great until some other markers (from the hand) gets into the head camera frame .

Do you have any suggestions how to avoid this problem ?
Any way to get Vector calculation although I have more than 3 markers in the head camera frame?
Do I need to calculate head 6DOF position by my self?
Is it possible to get this calculation from OPTITRACK?
Is there any way to use the SDK for this? for exsample I can determine which markers are the vector's and call an SDK function...

Any other ideas

Thanks
Mat

This sounds like a good candidate for our Point Cloud SDK which is due out very shortly. It allows 3D tracking of lots of arbitrarily placed markers simultaneously.

I'm going to try and get someone to update our web site with some of the latest screenshots so people can get a better idea of what's coming.

That would be great if you could do that.

The Point Cloud SDK has been updated with some screenshots.

Here's an additional screen shot using more cameras.

By early summer we hope to have a Point Cloud SDK available.

Thanks a lot for you suggestions,
Though I can't understand from the screenshots (and videos) if Point Cloud SDK will support Vector as an object and calculate its 6DOF while other dot/vector object will be tracked. From the information that was posted (screenshots and video) it was demonstrate only dots tracking.

Furthermore it will be very helpful as an SDK to introduce and share optitrack users\developers with some of the interfaces to be supported in the coming Point Cloud SDK.

Thanks
Mat

p.s.
Will it possible to get this aforementioned Vector calculation from the SDK (user will determine which markers are the vector's and call an SDK function which will calculate 6DOF) ?

I think you're going to need their rigid body tracking: http://www.naturalpoint.com/optitrack/p ... -body.html
