                         SbSphere()
                         SbSphere(const SbVec3f &center, float radius)
     void                setValue(const SbVec3f &center, float radius)
     void                setCenter(const SbVec3f &center)
     void                setRadius(float radius)
     const SbVec3f &     getCenter() const
     float               getRadius() const
     void                circumscribe(const SbBox3f &box)
     SbBool              intersect(const SbLine &l, SbVec3f &intersection)
                              const
     SbBool              intersect(const SbLine &l, SbVec3f &enter, SbVec3f

DESCRIPTION
     Represents a sphere in 3D. This is a lightweight datatype that is used
     for arguments or return values in the Inventor toolkit. See SoSphere for
     a database sphere (used for rendering, picking, etc.).

METHODS
                         SbSphere()
                         SbSphere(const SbVec3f &center, float radius)
          Constructors.

     void                setValue(const SbVec3f &center, float radius)
          Change the center and radius.

     void                setCenter(const SbVec3f &center)
     void                setRadius(float radius)
          Set just the center or radius.

     const SbVec3f &     getCenter() const
     float               getRadius() const
          Return the center and radius.

     void                circumscribe(const SbBox3f &box)
          Return a sphere containing a given box.

     SbBool              intersect(const SbLine &l, SbVec3f &intersection)
                              const
     SbBool              intersect(const SbLine &l, SbVec3f &enter, SbVec3f
                              &exit) const
          Intersect line and sphere, returning TRUE if there is an
          intersection. The line is treated as a ray.
