Maneuvering in 3D Space 11
First, lets look at the rotation based on the center. is type of rotation is accessed by
pressing the Alt/Option key while clicking the le mouse button, or by clicking and drag-
ging the rotation widget in the top-right corner of the viewport. As you drag up, down,
le, and right, the view shis around the focal point. is rotation technique keeps a set
distance from the center of view and always faces that point in space until another focus
is selected.
To rotate the view from a tripod, press Alt/Option and the right mouse button. e
tripod rotation works exactly like a real tripod: the orientation of the view is changed, but
the position of the view remains constant. is can be quite useful when working on large
scenes or architectural interiors. One thing to remember is that this option is specic to
views from cameras and lights, so the basic perspective view is not able to use tripod-
based rotation.

Using the right mouse button to rotate in the perspective view enables the view to rotate on
its own. As soon as you release the button, the view continues to spin, with the speed based
on the mouse speed when the button was released. Moving slowly allows for slow and sub-
tle rotation, while a quick flick of the mouse sends the view spinning rapidly. There is a falloff
of speed, and then the view comes to rest. This can also be done with the question mark (?)
key, which gives a single revolution around the scene.
