该法较好地解决了由计算对象边界复杂、材料分区多变带来的有限元三维网格自动剖分的困难。

The method overcomes the difficulty induced by complicated boundary and changeable materials of calculated objectives in auto-generation of the 3D FEM meshes.

因此，边界对象提供了一种交集，让不同的观点汇集到一起。

Thus a boundary object provides a kind of intersection where different points of view converge.

各种形状都既可以行进到极远处(射线)或停止在固定的距离上(分段)，你也可以基于一个边界对象做拣选。

Each of these shapes can either go on forever (a ray) or stop after a fixed distance (a segment), you can also pick based on a Bounds object.
