Multi-Camera
...
NSI has an elaborate camera description graph that allows for rendering of multiple points of views at once. Moreover, a single camera can be used to render multiple different screens. This is achieved by separating the camera's view description from the screen characteristics. Screen characteristics include such things as: resolution, crop and shading samples.
