<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>
