//! defines a LOD (level of detailization) node of VRML specifying properties <br>
//!          of geometry  and its appearance. <br>
//!  This  group  node  is  used  to  allow  applications  to  switch  between <br>
//!  various  representations  of  objects  automatically. The  children  of  this <br>
//!  node  typically  represent  the  same  object  or  objects  at  the  varying <br>
//!  of  Levels  Of  Detail  (LOD),  from  highest  detail  to  lowest. <br>
//! <br>
//!  The  specified  center  point  of  the  LOD  is  transformed  by  current <br>
//!  transformation  into  world  space,  and  yhe  distancefrom  the  transformed <br>
//!  center  to  the  world-space  eye  point  is  calculated. <br>
//!  If  thedistance  is  less  than  the  first  value  in  the  ranges  array, <br>
//!  than  the  first  child  of  the  LOD  group  is  drawn.  If  between <br>
//!  the  first  and  second  values  in  the  range  array,  the  second  child <br>
//!  is  drawn,  etc. <br>
//!  If  there  are  N  values  in  the  range  array,  the  LOD  group  should <br>
//!  have  N+1  children. <br>
//!  Specifying  too  few  children  will  result  in  the  last  child  being <br>
//!  used  repeatedly  for  the  lowest  lewels  of  detail;  if  too  many  children <br>
//!  are  specified,  the  extra  children  w ll  be  ignored. <br>
//!  Each  value  in  the  ranges  array  should  be  greater  than  the previous <br>
//!  value,  otherwise  results  are  undefined. <br>
