[vtkusers] VTK with Flock Of Birds Tracking System

[Alexander Soemer]

Hi,

i'm writing an application which maps ultrasound images to a
vtkPolyData-plane.

The position and orientation of the plane should be modified by data
from the Flock Of Birds tracking system. Therefore i need know how i can
get the data from the FoB, ie the X,Y,Z.. - values. I've just read that
somebody already worked on vtk classes which do that.

Does anyone know where to find these classes and whether they are free
to use?

Thanks
Alexander
