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

因此，边界对象提供了一种交集，让不同的观点汇集到一起。

For example, object bounding boxes may first be tested to see if polygon based testing is necessary - or bounding box intersection may often be all that is needed to provide acceptable results.

例如，首先可能要测试物体碰撞盒子，看是否需要基于测试的多边形，或者碰撞盒子交叉点可能经常成为提供满意结果的唯一来源。

This paper gives a method to generate a linear octtree of an object from its three orthogonal views using the volume intersection technique.

本文提出一种方法利用体积交技术由物体的正交三轮廓图生成它的线性八元树。
