User input device camera
Systems and methods for capturing a two dimensional (2D) image of a portion of a three dimensional (3D) scene may include a computer rendering a 3D scene on a display from a user's point of view (POV). A camera mode may be activated in response to user input and a POV of a camera may be determined. The POV of the camera may be specified by position and orientation of a user input device coupled to the computer, and may be independent of the user's POV. A 2D frame of the 3D scene based on the POV of the camera may be determined and the 2D image based on the 2D frame may be captured in response to user input. The 2D image may be stored locally or on a server of a network.
