Hi,

... 


I have two osga terrain model,A is a quite large country model,B is a quite 
small city model.

I just put the city model above the country model,then I zoom in to see the  
city model ,it seems to been culled.Then I set the near/far plane ratio to 
0.000001 which solve the problem,however it take great cpu usage(from 10% to 
60%),is there a better way to solve the problem?Thx!










Thank you!

Cheers,
Lv
