SbBox3f(3IV)

DESCRIPTION
     3D box which has planes parallel to the major axes and is specified by
     two points on a diagonal. This class is part of the standard Inventor
     datatype classes and is used as input and output to geometry operations
     (see SoGetBoundingBoxAction).

FUNCTIONS
     SbBox3f *		 SbBox3fCreate()
     SbBox3f *		 SbBox3fCreateBounds(float xmin, float ymin, float
			      zmin float xmax, float ymax, float zmax)
     SbBox3f *		 SbBox3fCreateMinMax(const SbVec3f *min, const SbVec3f
			      *max)
     voidvoid		 SbBox3fDelete(SbBox3f *this)
	  Constructors and destructor for a 3D float box. xmin, ymin, zmin,
	  xmax, ymax and zmax are the bounds of the box. min and max are the
	  corners of the diagonal that define the box.

     const SbVec3f *	 SbBox3fGetMinConst(SbBox3f *this)
     const SbVec3f *	 SbBox3fGetMaxConst(SbBox3f *this)
	  Returns the minimum and maximum points of the box. The minimum point
	  is the corner of the box with the lowest X, Y, and Z values. The
	  maximum point is the corner of the box with the highest X, Y, and Z
	  values.

     SbVec3f		 SbBox3fGetCenter(SbBox3f *this)
	  Returns the center of the box.

     void		 SbBox3fExtendByPt(SbBox3f *this, const SbVec3f
			      *point)
     void		 SbBox3fExtendByBox(SbBox3f *this, const SbBox3f *box)
	  Extends this box (if necessary) to contain the specified point or
	  other box.

     SbBool		 SbBox3fIntersectPt(SbBox3f *this, const SbVec3f
			      *point)
     SbBool		 SbBox3fIntersectBox(SbBox3f *this, const SbBox3f
			      *box)
	  Returns TRUE if the specified point or box intersects this box.

     void		 SbBox3fSetBounds(SbBox3f *this, float xmin, float
			      ymin, float zmin, float xmax, float ymax, float
			      zmax)
     void		 SbBox3fSetBoundsMinMax(SbBox3f *this, const SbVec3f
			      *min, const SbVec3f *max)
	  Sets the corners of the box.

     void		 SbBox3fGetBounds(SbBox3f *this, float *xmin, float
			      *ymin, float *zmin, float *xmax, float *ymax,
			      float *zmax)
     void		 SbBox3fGetBoundsMinMax(SbBox3f *this, SbVec3f *min,
			      SbVec3f *max)
	  Gets the corners of the box.

     void		 SbBox3fGetOrigin(SbBox3f *this, float *x0, float *y0,
			      float *z0)
	  Gets box origin which is the same as the minimum corner of the box.

     void		 SbBox3fGetSize(SbBox3f *this, float *x, float *y,
			      float *z)
	  Gets box size.

     void		 SbBox3fMakeEmpty(SbBox3f *this)
	  Makes an empty box.

     SbBool		 SbBox3fIsEmpty(SbBox3f *this)
	  Returns TRUE if the box is empty, and FALSE otherwise.

     SbBool		 SbBox3fHasVol(SbBox3f *this)
	  Returns TRUE if all three dimensions of the box have positive size,
	  and FALSE otherwise.

     void		 SbBox3fGetSpan(SbBox3f *this, SbVec3f *dir, float
			      *dMin, float *dMax)
	  Finds the span of a box along a specified direction. The span is the
	  total distance the box occupies along a given direction. The total
	  distance is returned in the form of a minimum and maximum distance
	  from the origin of each of the corners of the box along the given
	  direction. The difference between these two values is the span.

     void		 SbBox3fXf(SbBox3f *this, const SbMatrix *mx)
	  Transforms box by matrix, enlarging box to contain result.

     float		 SbBox3fGetVol(SbBox3f *this)
	  Returns the volume of the box.

FILE FORMAT/DEFAULTS
     Box3f {
     }
