Camera Controls

The first three buttons in the toolbar, as shown on the right, are the camera controls. The first item is a button which can be pressed to reset the view. The second two can be used to switch between a 3D and a 2D interaction mode. These are described in more detail below.

The reset button can be used to reset the camera so that all visible items will be in the viewing frustum. The current viewing direction will be maintained, but the camera and focal point will be translated, and the zoom factor will be adjusted so that all visible objects are in the view frustum. Items may still be hidden by another object.

The 3D movements interaction mode can be selected using the second button in the Toolbar. Generally the difference between 2D and 3D interaction is that 3D interaction allows rotation while 2D interaction allows only translation (panning). A rotation arrow is used to indicate the 3D interaction mode. Details of the 3D interaction mode can be found in the Camera Controls section of the 3D View Properties chapter.

The 2D movements interaction mode can be selected using the third button in the Toolbar.  An XY translation arrow is used to indicate the 2D interaction mode. Details of the 2D interaction mode can be found in the Camera Controls section of the 3D View Properties chapter.
