Chapter 12. Cameras > Creating Cameras

Creating Cameras

A camera is a nonrendering object that displays a view of a scene. The location and direction of the view is determined by the position and orientation of the camera.

Just as illumination can be considered an effect of a light, displaying a view can be considered an effect of a camera. To delimit a view, cameras use a field of view cone similar to the cone of illumination used by lights, except that the cone is actually pyramidal in shape. The angle of the cone ranges in arc from 0° to 175° across its width. The default field of view setting is 45°.
