| 摘 要： | 采用无缝LOD算法,将地形分割成不同分辨率的矩形节点,每个矩形由四个不同分辨率的三角形片和连接三角形的缝合带组成,实现了大规模地形的实时绘制,有效提高了地形绘制质量,绘制速度较传统LOD算法提高了近一倍。

| Abstract: | This paper presents a seamless LOD algorithm for interactive rendering.The terrain is subdivided into rectangle patches,each patch is presented by 4 triangle tiles which can be at different resolutions,and 4 stripes which are used to stitch the 4 triangles seamlessly.The quality of terrain has been improved and the rendering speed is nearly twice than the traditional method. |
