• derived nodes inherit all messages from their base classes
  
• see reset method for default settings
  
• this node can also be created with the alias: space
  
• a volume message defines a box, sphere, cylinder, point or infinite volume as follows:
  
  • volume(box [X Y Z X Y Z]) - default points (-0.5 -0.5 -0.5) and (0.5 0.5 0.5) define the extent of the box
    
  • volume(sphere [X Y Z radius]) - default the point (0 0 0) represents the origin of a sphere 0.5 in radius
    
  • volume(cylinder [X Y Z X Y Z radius]) - default points (0 0 -0.5) and (0 0 0.5) are the center of top and bottom circles 0.5 in radius
    
  • volume(point [X Y Z]) - default point is (0 0 0)
    
  • volume(infinite) - an infinite volume
