Re: [osg-users] DepthPartition

[MS]

Depth partition for long distances is a very old(90s-early 2000s) way to do
this type of effect.
Google reverse zbuffer and logarithmic depth buffer. The later can give you
galactic distances.

[osg-users] DepthPartition

[Infinite Reality]

Hi,
I have some problem(I guess it as depth issue) on rendering huge 
scene(solar system) using OpenSceneGraph.
But I found your depth partitioning can resolve it and it uses for 
rendering huge scene.
I tried to understand your internal implementation of depth partitioning 
using slave camera, but I was difficult to understand it clearly.
Can you explain how to works depth partitioning shortly?
Or any helpful reference is good for me.
Thank you in advance.
Cheers!
