The RoomAlive Toolkit is an open source SDK that enables developers to calibrate a network of multiple Kinect sensors and video projectors. The toolkit also provides a simple projection mapping sample that can be used as a basis to develop new immersive augmented reality experiences similar to those of the IllumiRoom and RoomAlive research projects.
The RoomAlive Toolkit is provided as open source under the MIT License. The code is available for download at GithHub: https://github.com/Kinect/RoomAliveToolkit.
Ben Lower and Andy Wilson gave a talk on the RoomAlive Toolkit for BUILD 2015. You can view it at http://channel9.msdn.com/Events/Build/2015/3-87.
