布什 RBush是用于点和矩形的2D空间索引的高性能JavaScript库。 它基于具有批量插入支持的优化R树数据结构。 空间索引是用于点和矩形的特殊数据结构,它使您可以高效地执行查询,例如“边界框内的所有项目”(例如,比遍历所有项目快数百倍)。 它最常用于地图和数据可视化。 演示版 该演示包含从5万个批量加载的随机点生成的树木的可视化。 打开Web控制台查看基准; 单击按钮以插入或删除项目; 单击以在光标下方执行搜索。 安装 使用NPM安装( npm install rbush ),或将CDN链接用于浏览器: , 用法 导入RBush // as a ES module import RBush from 'rbush' ; // as a CommonJS module const RBush = require ( 'rbush' ) ; 创建一棵树 const tree = new RBush ( ) ; RBush的可选参数定义了树节点中最大条目数。 9 (默认情况下使用)是大多数应用程序的合理选择。 较高的值表示更快的插入和较慢的搜索,反之亦然。 const t

This is the newly revised and expanded edition of the popular introduction to the design and implementation of geometry algorithms arising in areas such as computer graphics, robotics, and engineering design. The second edition contains material on several new topics, such as randomized algorithms for polygon triangulation, planar point location, 3D convex hull construction, intersection algorithms for ray-segment and ray-triangle, and point-in-polyhedron. A new "Sources" chapter points to supplemental literature for readers needing more information on any topic. A novel aspect is the inclusion of working C code for many of the algorithms, with discussion of practical implementation issues. The self-contained treatment presumes only an elementary knowledge of mathematics, but reaches topics on the frontier of current research, making it a useful reference for practitioners at all levels. The code in this new edition is significantly improved from the first edition, and four new routines are included. Java versions for this new edition are also available. All code is accessible from the book's Web site (http://cs.smith.edu/~orourke/) or by anonymous ftp.
