ViewAngle
ViewAngle
is 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 ViewAngle->All, 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.
- Explicit settings for ViewMatrix override settings for ViewAngle.
Use a specific half-angle for a simulated camera:
| Out[1]= |  |
The default 35° half-angle may not be enough for the particular ViewVector setting:
| Out[1]= |  |
Choose the half-angle automatically, so that the view includes all the objects:
| Out[2]= |  |
