[osg-users] first attempts with PagedLODs

[Daniel Lazaroff]

greetings all,

I've started trying out the DatabasePager with a test model of a small city landscape (openflight file) that has been converted into pagedLODs (I'm experimenting with load balancing of VRAM usage).
I used the "osgpagedlod.cpp" example to convert and write out the individual files (.ive). I'm using OSG 3.2
The individual buildings have discrete LODs and do not have overlapping ranges. As I move around the scene using the osgGA::TerrainManipulator, 
they pop in and out of the rendered scene, for a few frames no LOD is displayed. (due to the load time from disk of the files most probably)  

Is there something that I can do to alleviate this (tricks or tips)? I could try to overlap the ranges, but I read somewhere that this is not suggested.

Thanks for any info. 
Cheers

Daniel
