3D Scene Navigation

The 3D scene can be navigated to change the view of the scene being rendered to the UI preview window as well as the capture window. In desktop version of the software there is only one view port that is mapped to capture window and UI preview window. The capture window is exposed through a virtual camera interface. The Onyx compositing engine can take commands from user keyboard locally or can listen to commands coming from out-of-band communication channels from remote clients viewing the captured stream. These commands effect the view port used for capture and preview. This section lists the commands that can be given by the local user through keyboard and remote Skype video caller from his dial pad.

The commands can be interpreted meaningfully, if you can imagine yourself standing before a 3D structure and holding a camera. Imagine yourself moving in the structure and taking snapshots of the structure from various angles. The situation is similar to a camera man moving around in a studio and filming various objects. The navigation commands described here changes the location of the camera man and orientation of camera in the virtual studio.
