SYNOPSIS

       #include <Inventor/SbLinear.h>

          Methods from class SbSphere:

                         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 &exit) const

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.
