Presented in this paper is an accelerating hybrid rendering method for complex three-dimensional model using both point and polygon. On current PC hardware, the rendering method, which integrates advantages of both GBMR(graphics-based modeling and rendering) and PBMR(point-based modeling and rendering),works well with complex geometric models, which consist of millions of small triangles. In pre-processing phase, model faces are segmented into regions, then triangles and vertex point clouds of each region are stored together, and simultaneously all vertices are sorted in ascending order according to their important degree, and serialized to linear structure. In real-time rendering phase, view-dependent frustum culling and backface clipping are performed; different regions are rendered using point or triangle according to their distance from viewpoint. The above two phases sufficiently utilize the parallelism nature of GPU(graphic process unit) and efficiently implement a continuous multi-resolution rendering for HPPO (hybrid point and polygon object).
