Abstract
We present a storage format for placing multiple, dynamic 2.5D point sample streams (e.g. RGBZ video) or color video projections into the context of a common world space. The approach utilizes the concept of projective geometry to let virtual projectors "cast" the data from where it was originally recorded by the involved cameras. We exemplify the data format's versatility by demonstrating how several moving cameras reproduce 3D geometry exported from modeling software, and outline the extension to real-world acquisition. We also explain how this format can act as common interchange format for the camera parameters of lightfield/multi-view video footage.
