Tutorial - How to do 3d matching with VVVV and Voodoo Camera Tracker

This is the technical documentation of my project Syn Bio Ads, check the video underneath. It explains how to use the Voodoo Camera Tracker to match realworld filmed footage with a virtual 3D scene in VVVV. All necessary steps are explained step by step in the mini tutorial below.

The tutorial assumens that you use provide the sample image sequence /data/frames/frame-000000.png ... or that you have prepared your own image sequence.

Voodoo Camera Tracker

  1. File -> Open -> Sequence Chose an image sequence and chose the appropriate Move Type. I assume in this tutorial that the footage was filmed with a tripod (= camera was still in terms of XYZ and just the rotation of has to be matched). Hence select rotation (camera on tripod).

  2. View -> Camera Parameter, Tap "Position" Set Roll to 180°, to flip the camera from the upside down default value. Don't ask, I don't have a clue why upside down is default. Set Camera Parameters

  3. Press the Track button to create a 3D scene.

  4. View -> 3D Scene Viewer Check the result in 3D. Camera roll should be normal and not upside down. 3D Scene Viewer

  5. Save -> Texfile Check the "Export All" option to get really the whole scene geometry exported.


3D Scene Viewer VVVV

  1. Open voodoo_player_vvvv/_root_voodoo_test.v4p in VVVV
  2. Adjust the footage/frames and the voodoo file parameters to point to the correct locations. Depending of the source footage you might have to change the framerate pins, the example patch is set to 29.97 FPS.

That's it. From there one you are on your one :) Would be nice to see other projects using this technique/patch, feel free to drop an email to me.

Special thanks to: The makers of Voodoo Camera Tracker that they made the software free to use for non commercial projects! And Joreg who helped me to figure out how to translate the matrix defintions from Voodoo to VVVV speak!
