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.

MORE INFORMATION

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.

Basic Examples (2)

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:
