octree.js:Javascript Octree Quadtree 实现，专注于性能

八叉树 JavaScript Octree / Quadtree 实现，专注于性能仍有一些可能的性能改进领域。八叉树也可以用作四叉树，只需删除 Z 值。特征最大按位支持 AABB 和 POINT 无依赖 UMD 用法只需从 Octree.Item 继承您的对象并将其插入八叉树实例。 ... var octree = new Octree ( ) ; var item = new Octree . Item ( x , y , z , ex , ey , ez ) ; //ex,ey,ez is required only for AABB item octree . insert ( item ) ; var items = [ ] ; octree . retrieve ( item , items ) ; //retrieve items from octant of

This code snippet is calling a function called "radiusSearch" on an octree object, which takes in three arguments: "searchPoint" (the point to search around), "radius" (the search radius), and two empty arrays ("pointIdxRadiusSearch" and "pointRadiusSquaredDistance") that will be filled with the indices of the points within the radius and their squared distances from the search point, respectively. The function returns a value that is greater than 0 if there are any points within the specified radius of the search point.
