MPCDI
"The Multiple Projection Common Data Interchange (MPCDI) Standard developed by VESA’s Multi-Projector Automatic Calibration (MPAC) Task Group, creates a standard data format for multi-projector alignment systems, allowing these systems to produce data that can be easily utilized and integrated by a range of devices, programs and displays. The newest update includes a number of changes intended to mitigate color differences that arise when blending different projectors, enabling greater performance with respect to color consistency, brightness and intensity."[1]
