| 摘 要： | 提出一种用于建筑物环视系统混合绘制的加速方法,场景划分为主体模型和层次环境的带有深度的图像缓存(sprite with depth),采用BSP树存储场景的具有深度的图像缓存,用模型对存储场景的BSP树应用三维裁剪算法来减少不必要的绘制,并在环视过程中采用生成替代图像缓存方法,加速环视场景的生成.

An accelerated algorithm of rendering for sweeping outdoor buildings |
| |
| Abstract: | An accelerated method of rendering is proposed and used in sweeping outdoor buildings. In the scene, geometric models are used for main buildings and sprites with depth are used for closer scene elements. As a preprocessing step, this method constructs a BSP-tree that hierarchically partitions the sprites. Occlusion culling is used to cull the invisible sprites,and a substituted sprite based on viewport is used to improve the algorithm of rendering sprite with depth. |

| Keywords: | layered rendering sprite with depth visibility culling binary space partitioning tree forward warping |
