Axes appearance and behavior

View Control with the Camera Toolbar
The Camera toolbar enables you to perform a number of viewing operations interactively.

Camera Graphics Terminology
Graphics provides functionality, analogous to that of a camera with a zoom lens, that enables you to control the view of the scene.
Understanding View Projections
Graphics supports both orthographic and perspective projection types for displaying 3-D graphics. The one you select depends on the type of graphics you are displaying.
Low-Level Camera Properties
Camera graphics is based on a group of axes properties that control the position and orientation of the camera.
Setting the Viewpoint with Azimuth and Elevation
You can control the orientation of axes using graphics functions.
Dollying the Camera
The camdolly function allows you to move both the position of the camera and the position of the camera target in unison.
Moving the Camera Through a Scene
This example shows how to move a camera along a path traced by a stream line and how to move a light source with the camera.
Manipulating Axes Aspect Ratio
There are several axes properties that control the aspect ratio. Set these properties to achieve the effect you want.
