What does Multi-View Player do?

Multi-View Player is a tool developed in order to playback and explore .cdv files, which is the standard recording format of our Volumetric Capture system. User can not only view the recorded files in an effortless way, but also can dump color and depth images as well as pointclouds.

How does Multi-View Player work?

Multi-View Player can operate in two modes, one being as GUI (the default one) and the other being a command-line application (used for automated dumping). The software will run in GUI mode, unless it explicitly called from command line without the --gui argument.
