A Fast Culling Algorithm for Visualization of Terrain
This paper discusses a clipping method of using quadtree in terrain visualization and proposes some improvement techniques. The approach is based on the bounding sphere to culls large chunks of triangles. The algorithm is easy to implement and fast enough to achieve real-time culling in terrain visualization. Some examples illustrates the power of the approach.
