View source for Real-time Tracking for Live Preview

=== Introduction ===

'''Real-time Preview''' feature allows to perform tracking in real-time speed and instantly transfer motion to a 3D character for live preview right at the time of recording.

This feature allows [[iPi Recorder]] to communicate to [[iPi Mocap Studio]] software in a way similar to [[Distributed Recording]] to send data necessary for tracking. [[iPi Mocap Studio]] performs tracking and motion transfer at real-time speed. Feature benefits:
* User can see how the motion will look like on a 3D character at the time of performance.
* Ability to improve motion accordingly at the time of acting and recording without the need to redo multiple iterations of recording and offline tracking.

{{Note|Current version support only recording with single depth sensor. Adding support for multiple depth sensors is planned for Fall 2018.}}

=== Overview ===
The feature works like this:
* [[iPi Recorder]] broadcasts data necessary for tracking via network.
* [[iPi Mocap Studio]] connects to broadcasting [[iPi Recorder]] to start receiving data.
* [[iPi Mocap Studio]] performs tracking and motion transfer to a 3D character.
* Live tracking results can then be stored to disk for additional offline post-processing.
