Abstract
A set of viewpoints for a given scene of 3D objects is defined by a system that restricts the degrees of freedom available to a user, through use of a bounding surface (a viewpoint sphere), and provides varying degrees of automation ranging from predefined viewpoints to generated tour paths, to interactive selection using free navigation. The system calculates the scene sphere, which is the minimum bounding sphere that contains the set of objects in the scene and then finds the viewpoint sphere, which is done by calculating the viewpoint sphere radius. The user then chooses the mode of viewpoint selection as either completely automated, semi-automated, or free navigation. The output is a set of viewpoints for the given scene of objects.
