Sample Overview
Rim lighting is a common technique used in photography and
computer graphics. The technique puts a light source on the opposite side of
the object and away from the camera. This positioning is used to highlight the
silhouette of the object and to better separate it from the background.
The sample also provides a simple arcball class and a
ModelViewerCamera class. The arcball class handles rotations used internally in
ModelViewerCamera class. ModelViewerCamera actually uses two arcballs: one for
rotating the object in the World, and one for rotating the camera around the
object. When the camera is rotated around the object, its position changes, but
the camera is always looking at the object. This is similar to a satellite
circling earth, while its antenna always faces the earth.
