3D Holographic Video Chat [Kinect Hack]

It’s not great quality, and it’s over a year old, buuuut….

Real-time “holographic” video chat using two Kinect cameras to capture one participant, and a custom compression algorithm and network protocol to stream the resulting 3D video data across the Internet.

The other side of the conversation was filmed off a consumer 3D TV with a regular video camera.

The network protocol uses lossless compression using a Hilbert-curve traversal and run-length and delta encoding for the depth stream, and a Theora video codec for the color stream. The resulting bandwidth is about 750 kB/s for one Kinect camera.
