ViewVector

ViewVector
is an option for Graphics3D and related functions which specifies the position and direction of a simulated camera used to view three-dimensional objects.

MORE INFORMATION

With the default setting ViewVector->Automatic, the position and direction of the simulated camera is determined by the settings for ViewPoint and ViewCenter.

ViewVector->{x, y, z} specifies that the camera should be at the position with coordinates {x, y, z}, aimed in the direction specified by ViewCenter.

ViewVector->{{x, y, z}, {tx, ty, tz}} specifies that the camera should be aimed in the direction of the point {tx, ty, tz}.

Scaled coordinates can be used.

How much the simulated camera sees is determined by settings for ViewAngle and ViewRange.

Explicit settings for ViewVector override settings for ViewPoint and settings for ViewCenter of the form ViewCenter->{x, y, z}.

Explicit settings for ViewMatrix override settings for ViewVector.
