| 摘 要： | 提出了一种通过读取单色BMP格式的等高线图产生三维地形的方法。该方法对应每一个高程生成一个或多个多边形，再把代表不同高度的多边形放置到对应的高度上，并从最低端的多边形开始，逐层向上一层多边形采用沿各顶点法线放样的方法生成地形三角形。这种方法适用于生成锥形山、丘陵等小面积地区的地形模型。

| Abstract: | A method of generating 3D terrain, which based on 2-bits contour picture, was present. With this method, one or several polygons were built correspondingly to one contour. Then these polygons were put to their elevation level, and lofted from the bottom polygon to the next one, till to the top. A new loft way called vertex loft was used to generate triangles. This method can be used to generate random terrain and taper hills. |
