Public Class Methods
new(*args)

Returns an initialized FXGLSphere instance.
One option is to initialize the sphere with a specified origin and radius:
aSphere = FXGLSphere.new(x, y, z, r)
If left unspecified, the radius (r) defaults to 1.0.
Another option is to initialize the sphere with a specified origin, radius and material:
aSphere = FXGLSphere.new(x, y, z, r, material)
where the material is an FXMaterial instance.
