多分辨率模型表面简化算法用一简单的模型来近似表示原始的高分辨率模型，减少模型表示的多边形数，从而加速场景绘制。

Many resolution ratio model surface simplify algorithm come with one simple model approximate to say the primitive high-resolution model, reduce polygon that model show count, accelerate scene draw.

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.
