## Camera Primitives

Camera primitive presets can be used with either the X3DObject.AddPrimitive or X3DObject.AddCamera methods or one of the camera-creation commands (GetPrimCamera, SIGetPrimCamera). All camera types use the same set of camera parameters configured differently.

Note | See Primitive Presets for list of the possible types of primitives. Also see Alphabetical Listing of All Primitive Presets for a complete list of available primitive types.

Preset | Primitives
--- | ---
Camera | Perspective cameras use a perspective projection, which simulates depth and are useful for simulating a physical camera. The default camera in any new scene is a perspective camera.
Orthographic | Orthographic cameras make all of the camera rays parallel. Objects stay the same size regardless of their distance from the camera. These projections are useful for architectural and engineering renderings.
Telephoto | Telephoto cameras use a perspective projection and a small angle of view (5°) to simulate a telephoto lens view where objects are zoomed.
Wide_Angle | Wide angle cameras create a wide-angle view by using a perspective projection and a large angle (100°) of view. Wide angle cameras have a very large field of view and can often distort the perspective.
