Does osgEarth have the ability to dump its messages to a log or text file?
For example, rather than having a message like "[osgEarth]* [TileSource] Open failed: Failed to open dataset Z:\TerrainDataDT1\terrain.tif" that prints to the console, it could be redirected to a file instead.
If osgEarth has this capability, how do I enable it?
No, it always writes to std::cout (or std::cerr). The osgEarth/Notify code is mostly just copied from an old version of osg/Notify. I think the latest osg/Notify stuff lets you set a custom handler. You could port that over the osgEarth without much difficulty, probably. -gw
