I can't find any good tutorial out there that teaches this topic. Is there any 3D guru that will teach or give me a link on how to create a Quadtree and Frustum? I want to load a 512x512 heightmap then use quadtree and frustum on it. Does player's model will also be included on it to save rendering time?
By the way, this is a bit different topic but what is scene graph in short and how can I implement it here?
