VR Camera
 | VR Camera | This node provides camera data from Trackmen tracking solutions for e.g. virtual studios. |
The VR Camera content nodes provides a simple way of generating a view and projection matrix based on common values gathered from camera tracking systems used in virtual studios. A real camera has a position and an orientation in the studio (view matrix) as well optical parameters expressed by the lens, such as zoom, focus and center shift (projection matrix).
The VR Camera has a Manual operation mode where the input properties Position, Direction, View and Center are used to generate these two matrices. These matrices VRView and VRProjection have to be connected to a View Node and a Projection Node to view your virtual scene through that camera. If Manual is disabled the camera data is taken from the connected tracking system, which has to be configured in the Machine Configuration.
The advantage of the Manual mode is also that tracking systems not directly supported by Ventuz can easily connected via normal Bindings. MIDI, OSC or Script Nodes could provide third party tracking data.
The VR Camera Node also gives information about the camera parameters actually used to generate the matrices. This gives the opportunity to use these values for effects like zoom-dependent-studio-rotations.
