Hi,
... Hi,
I have a VPB generated terrain model (.osga),about 4000KM*4000KM and near 3 G.
When I use osg2.8.4 viewering this model ,it cost me 15%~25% cpu usage.
I also make a province boundary layer model using OSGGIS,it convers some vector
shp file to a .ive model (all lines) which is

Hi,

I mean why viewering a much small model (3.5mb) takes as much cpu usage as a
large one(3.0G)?
Thank you!
Cheers,

Your large model uses sophisticated heirarchical LOD techniques to not ever
have all the
large data in memory at once.
