< BLOCKQUOTE > LOD - Level Of Detail group node which allows switching between children
depending on distance from eye point.
Typical uses are for load balancing - objects further away from
the eye point are rendered at a lower level of detail, and at times
of high stress on the graphics pipeline lower levels of detail can
also be chosen.
The children are ordered from most detailed (for close up views) to the least
(see from a distance), and a set of ranges are used to decide which LOD is used
at different view distances, the criteria used is child 'i' is used when
range[i]< dist < range [ i + 1 ] is true . This requires there to be n + 1 range values where the number of
children is n, since no maximum distance of infinity is assumed. If the number of range values (m)
is insufficient then the children m through to n will be ignored, only 0..m-1 will be used
during rendering.< / BLOCKQUOTE >
