The test showed that the average production time overlapped by the complex terrain of buildings, roads and vegetation is 15.96 seconds, thus realized the roam in the complex 3-d scene fluently.
测试得知，叠加了建筑物、道路、植被的复杂地形的平均生成时间为15.96秒，实现了复杂三维场景的流畅漫游。
Then the method of 3-d terrain modeling based on regular grid is studied.
然后研究了基于规则格网的三维地形建模方法。
By using these two methods, hidden surfaces are removed effectively. After shading treatment 3-d terrain pictures reflecting the real situation and remote sensing images are obtained.
这两种方法都能有效地进行隐面消除，并通过明暗处理获得了真实感较强的立体地形图和三维遥感图。
