Hi Amkita, The OSG doesn't provide any support for this type of user interaction so you'll have to add it yourself. The OSG primarily focus is rendering rather than model editing building, to do the later you'll have to add extra functionality on top. There is chance that members of the OSG

Hi Nick, For normal OSG usage you shouldn't need to worry about explicitly trying to call releaseGLObjects(). The only case where this might be needed is you detact a scene graph from viewer then destroy the viewer, but retain the scene graph so it doesn't get cleaned, but then you go an apply
