| Abstract: | In this paper, a 3D visualization method for mass real-time model data was proposed. Real-time data transmission, loading, and graphics memory written-in were achieved by using multi-threaded technology. The smooth transformation and anti-dithering for models were realized by GPU. Based on the establishment of multi-level-of-detail ( LOD) simplification and instanti-ation technology, the rendering performance optimization of massive data was achieved. Experiments show that the proposed method ef-fectively enhances the rendering performance and rendering effect of massive real-time data. |
