If i derive a class from osg:drawable ( say like osg::Text ) what are the functions that I should surely overload ?. One is DrawImplementation function. Are ther any other Functions that i should surely overload . You only need override pure virtual methods, and drawImplementation() is the only pure virtual method in the Drawable class. Depending on what you're doing, you might also want to override the destructor, or computeBound(), but this isn't strictly required and, as I said, depends on what you're doing.
