Crash at poles #809

Closed jasonbeverage closed 8 years ago

jasonbeverage commented 8 years ago

osgearth will continuously subdivide and crash if you use rex (or mp with a high min_lod set) and zoom into the poles. It will continue to subdivide and eventually run out of memory.

Run osgearth_viewer readymap-rex and go zoom into the north pole to reproduce.

Maybe we limit how far down osgearth can subdivide based on latitude.

Fixed by changing the adaptive polar algorithm to adjust the perceived tile radius based on latitude
