lating the view of your model:

Changing the View Projection
You can choose to view your model in Perspective
view or in one of several orthographic views.
You can use any of the following methods to access
the view projection controls.
The Lightscape perspective camera model uses a
viewer position, a focus point, and a picture plane to
create the perspective views. Both the View Setup
tool and the interactive view controls are based on
these conventions, as illustrated in the following
diagram.
You can set up a view camera by specifying the loca-
tions for the viewer position, focus point, view
angle, and picture plane with the View Setup
controls. There are also interactive controls for
changing your view of the model.
