在本教程中，我們將提出一個 O（nm）的碰撞檢測算法，適用於檢測精確三維模型之間的碰撞含N和M三角形。 不過，如果你需要檢查碰撞更複雜的對象，你可以隨時創建中間包圍盒，降低了算法的順序。-In this tutorial, we will propose an O (nm) of the collision detection algorithm for accurate detection of the collision between three-dimensional model with N and M triangles. However, if you need to check the collision of a more complex object, you can always create the intermediate bounding box, reducing the order of the algorithm.
