roll [-absolute]
[-degree angle] [-relative] [camera]
roll is undoable, NOT queryable, and NOT
editable.
The roll command rotates a camera about its viewing direction, a
positive angle produces clockwise camera rotation, while a negative
angle produces counter-clockwise camera rotation. The default mode
is relative and the rotation is applied with respect to the current
orientation of the camera. When mode is set to absolute, the
rotation is applied with respect to the plane constructed from the
following three vectors in the world space: the world up vector,
the camera view vector, and the camera up vector. The rotation
angle is specified in degrees. The roll command can be applied to
either a perspective or an orthographic camera. This command may be
applied to more than one camera; objects that are not cameras are
ignored. When no camera name supplied, this command is applied to
all currently active cameras.
