Three-Point Infrared Tracking Interaction

Explore three-point near-infrared sensing to estimate distance, rotation and tilt relative to a projection surface.

The source specifies two users and potential artifact-assembly, restoration-demonstration and alignment interactions. Tracking algorithms and calibration need validation.
