RE: [Algorithms] View-Depend vs. View-Independent LOD

[Daniel R. <dan...@ho...>]

(think about progressive mesh / mmr lod)
if you would crate a big landscape an choose its triangle
count via lod and change it completely it's View Independant

if you use a algorithm to calculate which landscpae
point should be colapsed you will do that mostly
via: far away => many collapses
     near => few collapes
and so this far/near is View Dependant

hope this helps, re...@ma...
