ViewVertical

ViewVertical is an option for Graphics3D and SurfaceGraphics which specifies what direction in scaled coordinates should be vertical in the final image.

The default setting is ViewVertical -> {0, 0, 1}, which specifies that the axis in your original coordinate system should end up vertical in the final image.

The setting for ViewVertical is given in scaled coordinates, which run from 0 to 1 across each dimension of the bounding box.

Only the direction of the vector specified by ViewVertical is important; its magnitude is irrelevant.

See The Mathematica Book: Section 2.9.10.
