碰撞检测和响应可以使虚拟现实应用程序看起来更可信。不幸的是，现有的碰撞检测算法速度太慢，无法进行交互使用。作者提出了一种新的算法，它不仅速度快，而且可中断，允许应用程序以质量换取更快的速度。该算法使用简单的四维几何来逼近运动，用球面集合来逼近三维曲面。该算法使样本应用程序的运行速度比现有算法快五到七倍。
Collision detection and response can make a virtual-reality application seem more believable. Unfortunately, existing collision-detection algorithms are too slow for interactive use. The authors present a new algorithm that is not only fast but also interruptible, allowing an application to trade quality for more speed. The algorithm uses simple four-dimensional geometry to approximate motion, and sets of spheres to approximate three-dimensional surfaces. The algorithm allows a sample application to run five to seven times faster than it runs with existing algorithms.>
