Clone the type of an object, with Object* return type.

drawImplementation(RenderInfo&) is a pure virtual method for the actual implementation of OpenGL drawing calls, such as vertex arrays and primitives, that must be implemented in concrete subclasses of the Drawable base class, examples include osg::Geometry and osg::ShapeDrawable.
drawImplementation(RenderInfo&) is called from the draw(RenderInfo&) method, with the draw method handling management of OpenGL display lists, and drawImplementation(RenderInfo&) handling the actual drawing itself.
- Parameters:
-
renderInfo | The osg::RenderInfo object that encapsulates the current rendering information including the osg::State OpenGL state for the current graphics context. |
Implements osg::Drawable.
return the name of the object's library.
Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.
Reimplemented from osg::Drawable.
