Real-time rendering for large-scale, complex dynamic virtual scenes is a challenging problem in computer graphics. In this paper, we propose a hybrid rendering algorithm of dynamic virtual environments that seamlessly fuses the point-based scheme and polygon-based scheme. In our algorithm, the scene is organized into a BSP-tree. Objects in the leaf-nodes of the BSP tree are further subdivided into a quad-tree hierarchy, which contains both the sample points and polygon rendering information at each level. The accelerated rendering algorithm integrates the hierarchical occlusion map technique, image caching technique and BSP technique to fast render complex dynamic scenes. During navigation, our system adaptively determines the rendering mode and the level of details of objects, and achieves smooth transition between the two rendering modes by effectively controlling the rendering precision. The dynamic objects can be processed in the system uniformly. Our experimental results have demonstrated the satisfactory performance of the proposed hybrid-rendering scheme for the dynamic virtual environments.
