A dynamic loading mechanism for large-scale 3D visualization

In this paper, we provide an effective memory management mechanism to handle massive 3D data. No matter what data it is, we selectively loading 3D data we just need, basing on view frustum, camera direction, distance and some restrictions which we can easily define. We use BVH (Bounding Volume Hierarchy) to organize scene data. And create two level to handle node loading and computer graphics rendering separately. After implement the system, we so some experiment use 3D scene data. The result shows that our mechanism has higher usage of computer memory and rendering more stably.
