# ViewAngle

 ViewAngleis an option for Graphics3D and related functions which gives the opening half-angle for a simulated camera used to view the three-dimensional scene.
• The following settings can be used:
 All an opening half-angle sufficient to see everything Automatic a maximum opening angle of (default) an explicit half-opening angle in radians
• With the setting , the complete bounding box or circumscribing sphere will, if possible, just fill the final 2D viewing area.
• The default setting of Automatic is equivalent to All when the simulated camera is far from the object, but is constrained never to be greater than , even when the camera is close.
• ViewAngle->35Degree is a typical field of view used for human ergonomics and in cameras.
• Changing the setting for ViewAngle is effectively like zooming a camera.
Use a specific half-angle for a simulated camera:
The default 35° half-angle may not be enough for the particular ViewVector setting:
Choose the half-angle automatically, so that the view includes all the objects:
