The Camera Optics panel.
For a comprehensive technical description of all the features supported by cameras in Arion, please refer to this area of the Knowledge Base.
RHINO LIVE takes the basic camera properties (i.e., position, direction, and target distance) from the current active view in the Rhinoceros document. The rest of extended optics and photographic properties (e.g., f-stop, shutter speed, ...) are taken from the RHINO LIVE Camera Optics panel.
The Camera Optics panel can be opened from the RandomControl LIVE entry in the top menu bar.
