[osg-users] isolate specific LOD from a VPB generated database

[Nickolai Medvedev]

I try to create similarity of a game, and in the future i will need to realize
the big open world too. I experimented with creation of a terrain from a
heightmap, i managed to create it, but inconsistencies still are.
My problem - i nothing understand in the math, it would help me.

About your question: Maybe you need add each LOD to osg::Switch, turn off
all of them, then turn on only that which is necessary to you.

I hope, i helps something...
