3-D Visualization

Default Viewpoint Selection

When all the camera mode properties are set to auto (the default), MATLAB automatically controls the view, selecting appropriate values based on the assumption that you want the scene to fill the position rectangle (which is defined by the width and height components of the axes Position property).

By default, MATLAB:

• Sets the CameraPosition so the orientation of the scene is the standard MATLAB 2-D or 3-D view (see the view command)
• Sets the CameraTarget to the center of the plot box
• Sets the CameraUpVector so the y-direction is up for 2-D views and the z-direction is up for 3-D views
• Sets the CameraViewAngle to the minimum angle that makes the scene fill the position rectangle (the rectangle defined by the axes Position property)
• Uses orthographic projection

This default behavior generally produces desirable results. However, you can change these properties to produce useful effects.
