ViewAngle

ViewAngle

is an option for Graphics3D and related functions that gives the opening angle for a simulated camera used to view the three-dimensional scene.

Details

  • The following settings can be used:
  • Allan opening angle sufficient to see everything
    Automatica maximum opening angle of 35^◦ (default)
    θan explicit 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 35^◦, 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.

Basic Examples  (2)

Use a specific angle for a simulated camera:

The default 35° angle may not be enough for the particular ViewVector setting:

Choose the angle automatically, so that the view includes all the objects:
