I've noticed some weirdness with the TerrainManipulator. I assume this is a bug but maybe not?
The simplest way to produce this behavior is to run osgviewer and feed it something. I've been feeding it a globe of the blue marble data created using the osgdem tutorial page. This is the older vpb/osgdem format. I assume the behavior is the same with the new stuff. Ok next I have my globe and everything is hunky dory. Now I zoom in to look somewhere on the earth surface. I rotate the camera using left mouse so that the camera is BELOW the terrain of the point I was looking out. Now I zoom out so that the camera comes out the opposite side of the earth. I'm now looking at a point directly on the other side of the earth from where I was looking at a second ago. Now if I try to pan the terrain (middle mouse) things are screwed up and directions are reversed. It looks like the math is not able to handle this type of scenario. I have a recent version of Open Scene Graph (v 2.9.0) from the trunk (about a week or so old). Thanks -Brad
