DESCRIPTION

       2D  box  which  has  planes  parallel  to  the  major  axes and is specified by two points
       (specified as floating point) on a diagonal. This class is part of the  standard  Inventor
       datatype classes and is used as input and output to geometry operations.

METHODS

                         SbBox2f()
                         SbBox2f(float xmin, float ymin, float xmax float ymax)
                         SbBox2f(const SbVec2f &min, const SbVec2f &max)
     void                ~SbBox2f()
          Constructors  and  destructor  for  a  2D float box. xmin, ymin, xmax, and ymax are the
          bounds of the box. min and max are the corners of the diagonal that define the box.

     const SbVec2f &     getMin()
     const SbVec2f &     getMax()
          Returns the minimum and maximum points of the box.

     SbVec2f             getCenter()
          Returns the center of the box.

     void                extendBy(const SbVec2f &point)
     void                extendBy(const SbBox2f &box)
          Extends this box (if necessary) to contain the specified point or other box.

     SbBool              intersect(const SbVec2f &point)
     SbBool              intersect(const SbBox2f &box)
          Returns TRUE if the specified point or box intersects this box.

     void                setBounds(float xmin, float ymin, float xmax, float ymax)
     void                setBounds(const SbVec2f &min, const SbVec2f &max)
          Sets the corners of the box.

     void                getBounds(float &xmin, float &ymin, float &xmax, float &ymax)
     void                getBounds(SbVec2f &min, SbVec2f &max)
          Gets the corners of the box.

     void                getOrigin(float &x0, float &y0)
          Gets box origin.

     void                getSize(float &x, float &y)
          Gets box size.

     float               getAspectRatio()
          Gets box aspect ratio.

     void                makeEmpty()
          Makes an empty box.

     SbBool              isEmpty()
          Returns TRUE if the box is empty, and FALSE otherwise.

     SbBool              hasArea()
          Returns TRUE if both dimensions of the box have positive size, and FALSE otherwise.
