I've started looking at code, but have no familiarity with this codebase, and time is very limited. I was wondering if someone code offer assistance on code, as in what functions to look at. I was looking at osgGA src, and found Animation path code, and in osgViewer/ViewerEventHandlers.cpp the part where it switches to animation path camera, but I'm not sure where to look to start playing around with code, since I don't know how it works yet. Just looking for additional details that help me get started on problem. Thanks.
