Detailed Description

A class that provides a simple means to draw a 3D sphere shape.

A sphere is specified by a position and radius.

This class handles all vertex and index buffer generation automatically, simplifying the visualization of spheres, such as for collision geometry. Internally, this class automatically chooses the proper geometric level of detail for the sphere representation in order to acheive nearly pixel-perfect accuracy when rendering from any perspective.
