在这篇文章中我们将会学习四叉树 quadtrees,并学习如果通过四叉树跳过那些物理空间距离比较远的对象,最终提高碰撞检测速度。 注:原文中使用Java实现,但是考虑目前多产品是基于Unity3D,故采用C#进行相关实现说明。 IntroDuction 碰撞检测Collision detection对于视频游戏来说是非常必要的。无论是2D游戏或是3D游戏中,正确的...
这里简单实现了一下AABB,总的来说很简单,就不在这里赘述了。 这样我们就在Unity里简单实现了四叉树,四叉树的应用还是很广泛的,尤其是在做地图管理方面。 划线 用递归给每个子树的轮廓划线就可以了 Reference: [1]cr4yz/Unity3d-QuadTree-Collision-Detection...

根據上述步驟,在QuadTree中加入query這個function : query(range,found){// 如果沒有給定回傳的陣列,就建立一個if(!found)found=[];// 判斷搜尋範圍(range)是否與當前領域有相交,沒有就直接跳掉,以節省效率if(!CheckCollision(this.boundary,range))return;// 如果搜尋範圍跟當前領域相交,檢查該領域有多少物體包...
遍历即可。注意，判断时需排除自身所在区域。此处使用ReferenceEquals。碰撞检测简单实现了AABB，此处不再赘述。在Unity中实现四叉树相对简单，四叉树的应用十分广泛，尤其在地图管理方面。划线时，可使用递归为每个子树的轮廓划线。Reference：[1] cr4yz/Unity3d-QuadTree-Collision-Detection ...
Additionally, this project will implement quadtree algorithms and use it to do collision detection. However, if apply classic quadtree to collision detection, the efficiency is not satisfying due to many cross-sides objects. Inspired by Hanan Samet and their demo on the website[2], this project...

dividing each square into four equally-sized squares. Each distinct point exists in a unique leafnode; coincident points are represented by a linked list. Quadtrees can accelerate various spatial operations, such as theBarnes–Hut approximationfor computing many-body forces, collision detection, and ...
This is a JavaScript Quadtree implementation based on the Java Methods described ongamedevelopment.tutsplus.com by Steven Lambert: Many games require the use of collision detection algorithms to determine when two objects have collided, but these algorithms are often expensive operations and can greatly...
