QuadTree四叉树顾名思义就是树状的数据结构,其每个节点有四个孩子节点,可将二维平面递归分割子区域.QuadTree常用于空间数据库索引,3D的椎体可见区域裁剪,甚至图片分析处理,我们今天介绍的是QuadTree最常被游戏领域使用到的碰撞检测.采用QuadTree算法将大大减少需要测试碰撞的次数,从而提高游戏刷新性能,本文例子基于HT for Web的Canvas拓扑图和WebGL的3D引擎组件,通过GraphView和Graph3dView共享同一数据模型DataModel,同时呈现Qua
The following are few examples of game engines implemented with HTML5 and JavaScript: Construct 2: One of the first WebGL enabled HTML5 game engines. Exports purely to HTML5 and JavaScript. Uses Canvas only and is extensible with JavaScript plugins.
