Camera tracking tutorial with Blender and Voodoo

Here is a great tutorial on how to do camera tracking in Blender, using the Voodoo camera tracker. The Voodoo software can estimates camera parameters, like position and rotation and reconstructs a 3d scene from image sequences.

At the tutorial, a virtual object is placed in real footage. All credits for the tutorial goes for Sympodius, from the BlenderArtists forums.
