Detailed Description
The ArcBall class defines tools for rotating and viewing three-dimensional images.
When viewing three-dimensional objects there are many different ways to choose a viewpoint. The basic principle is to create a sphere around a chosen object and then, by choosing a point on that sphere, drag that point to a different location and have the object rotate in a way defined by a rotation around the arc-ball.
Rotations are mapped onto a quaternion.
