[osg-users] Large number of occluder nodes

[David Heitbrink]

We do have a city scene at ground levels with lots of cars, pedestrian, construction zone clutter. The cars tend to be the worst as they can have up to 8 transparent object each from them. Large parking lots can have 500+ vehicles. 

OK so it sounds like what we need to do is to try to combine occluder nodes the best we can. These were generated via a script and placed in the center of each building...we just have lots of building with alleys between them. 

It also sounds like we will need to come up with some sort of paging/LOD scheme ourselves to remove nodes more than say 2500m from the camera.
