    3D Visualization The output of the tracking module is the input for the 3D visualization block implemented in Blender. Blender [20,21] is a free open source 3D content creation suite, available for all major operating systems under the GNU General télécommande wii Public License. A Python script receives marker coordinates from the tracking module and the alignment matrix from the calibration module (over an UDP socket). The four cameras, the WCS, and the tracked télécommande wii object are placed into a 3D environment (for instance, see Fig. 7).

    An X-UFO ying session on the télécommande wii left (two stirrups on the background) and the virtual reconstruction of X-UFO position and orientation on the right. Spheres represent the four cameras; the two highlighted spheres are those currently tracking the télécommande wii target (The WCS is also clearly visible). If the 3D geometry of the rigid-body currently tracked is available, a real-time virtual reconstruction of the object movements can be displayed.
