void  Box (gp_Pnt &P, gp_Vec &V1, gp_Vec &V2, gp_Vec &V3) const 
Returns the definition of the smallest box which contains all the points analyzed by this framework if, according to the given precision value, the points are considered to be neither coincident, nor collinear and nor coplanar. This box is centered on the barycenter P of the collection of points. Its sides are parallel to the three vectors V1, V2 and V3, the length of which is the length of the box in the corresponding direction. Note: Vectors V1, V2 and V3 are parallel to the three axes of principal inertia of the system composed of the collection of points where each point is of equal mass. Exceptions Standard_NoSuchObject if, according to the given precision, the points analyzed by this framework are considered to be coincident, collinear or coplanar. More...
