基于顶点对迭代收缩的表面简化方法，提出一种建筑物多分辨网格的生成与显示算法。
A novel algorithm based on iterative edge contraction surface simplification method was proposed to (generate) and display the multi-resolution building meshes.
在这个例子里，圈饼表面就是非单连通的，并且这类物体的简化就会像是至少有一个洞的曲面。
In this example, the surface is not simply connected and any smoothed-out object looks like a torus with at least one hole.
任何具有单连通表面的物体都能简化成一个球体。
Any object with a simply connected surface can be smoothed out to look like a sphere.
