ok, your device gives you the origin and rotation of a coordinate system
and you (presumably) want to visualize one of the axis' of this
coordinate system. Build a Geometry that contains a line along the axis
you want to visualize (for x axis you'd use points (0,0,0) (1,0,0)) and
put it under a Transform. Update that Transform's matrix with the data
from the device.
