"Summary of changes: From Roland -Added MorphGeometry -Bone Bindmatrix is only calculated if needed -osgAnimation plugin now supports all available channel types (before only linear vec3 or quat channels) -osgAnimation plugin now supports MorphGeometry -osgAnimation plugin now supports animation and channel weights, animation playmode, duration and starttime -removed osgAnimationManager.cpp from CMakeList From Cedric -fixed the last_update field (it was only updated at the first update) in BasicAnimationManager.cpp - Refactore some part of MorphGeometry minor changes - Add osganimationmorph as example "
