[osg-users] Strategy for implementing dynamic vertical exaggeration of VPB models.

Hi, When creating globes with VPB one can use the option -v (vertical multiplier) to set permanent vertical exaggeration for the generated model. However, in our software solution the user must be able to set vertical exaggeration from the GUI (i.e. dynamically alter vertical exaggeration).

[osg-users] Intermittent crashes in osgTerrrain::Terrain::traverse(...) [SingleThreaded]
