| 摘 要： | 三维地形场景的真实感绘制追求的两个目标是绘制的逼真度和绘制的实时性，需要在不明显降低图像质量的条件下保持较高的交互帧速率。为了满足实时性的需求，采用连续LOD算法和其它技术来加速地形绘制：为了满足逼真度的需求，采用SAR图像进行纹理映射，采用光照映射实现场景照明和明暗处理。

| Abstract: | Realistic rendering of 3D terrain scenes has two aims,which are reality of rendering and real-time of rendering.It
should maintain higher interactive frame rates without noticeably degrading image quality.For the purpose of real-time,continuous
LOD algorithms and other techniques were used to accelerete terrain rendering.For the purpose of reality,SAR image was used
to texture mapping,and lightmapping was used to scenes illumination and shading. |

| Keywords: | realistic rendering levels of detail texture mapping lightmapping image based rendering quadtree SAR image |
