Bnd_Box Class Reference

Describes a bounding box in 3D space. 
A bounding box is parallel to the axes of the coordinates 
system. If it is finite, it is defined by the three intervals: 

• [ Xmin,Xmax ], 
  
• [ Ymin,Ymax ], 
  
• [ Zmin,Zmax ]. 
  A bounding box may be infinite (i.e. open) in one or more 
  directions. It is said to be: 
  
• OpenXmin if it is infinite on the negative side of the "X Direction"; 
  
• OpenXmax if it is infinite on the positive side of the "X Direction"; 
  
• OpenYmin if it is infinite on the negative side of the "Y Direction"; 
  
• OpenYmax if it is infinite on the positive side of the "Y Direction"; 
  
• OpenZmin if it is infinite on the negative side of the "Z Direction"; 
  
• OpenZmax if it is infinite on the positive side of the "Z Direction"; 
  
• WholeSpace if it is infinite in all six directions. In this 
  case, any point of the space is inside the box; 
  
• Void if it is empty. In this case, there is no point included in the box. 
  A bounding box is defined by: 
  
• six bounds (Xmin, Xmax, Ymin, Ymax, Zmin and 
  Zmax) which limit the bounding box if it is finite, 
  
• eight flags (OpenXmin, OpenXmax, OpenYmin, 
  OpenYmax, OpenZmin, OpenZmax, 
  WholeSpace and Void) which describe the 
  bounding box if it is infinite or empty, and 
  
• a gap, which is included on both sides in any direction 
  when consulting the finite bounds of the box.
