VVVV * Mapping workshop at University of Seoul

Friday, August 26th, 2011

All this week we’ve been with a VVVV hungry bunch at University of Seoul(서울시립대학교). Minha Yang‘s talented art/design students came up with a range of challenging and intriguing ideas, and then patched them up in our favourite multipurpose toolkit VVVV.

After 4 days, the students were tracking motion, visualising sound, mapping onto 3D objects/architecture, creating multi-layered content, capturing video, and making complete interactive installations.

We were very much impressed with every student, and they all worked hard to absorb a range of patching concepts and styles. Awesome bunch. Watch out for them!

 

Kinect + Projector experiments

Wednesday, January 12th, 2011

Using Padé projection mapping to calibrate Kinect’s 3D world with a projector.

  1. Using the kinect camera, we can scan a 3D scene in realtime.
  2. Using a video projector, we can project onto a 3D scene in realtime.

Combining these, we re-project images onto geometry to create a new technique for augmented reality

The pipeline is:

  1. Capture Depth at CameraXY (OpenNI)
  2. Convert to image of WorldXYZ
  3. Pade transformation to create WorldXYZ map in ProjectorXY
  4. Calculate NormalXYZ  map in ProjectorXY
  5. Guassian Blur X of NormalXYZ in ProjectorXY
  6. Guassian Blur Y of NormalXYZ in ProjectorXY
  7. Light calculations on NormalXYZ, WorldXYZ maps in ProjectorXY
