I'm doing a performance where I scan the performers silhouette with Kinect and then change that "Alpha Mask" with content imported by syphon.

This is supposed to be projected into a wall where the performers are but I'm having problems calibrating the projector point of view with kinect's point of view so the projection on the bodies match up correctly.

I'm using the SimpleOpenNI/NITE/OpenNI library in processing.

I'm trying to do something like in this clip,

I really need your help,

thanks in advance.
