I’m building a 2d game engine using c++ and opengl. Now i have implemented a scene graph and now every node of this graph is being rendered every frame. What are good algorithms for clipping nodes that are outside the viewport?

at a most simple level, you could use quadtrees for culling, it has the added bonus of being useful for collision detection as well, Wikipedia has a page explaining it.
