I am writing a removal method for a quad tree. Now when you remove an item in a node, you will need to check its siblings to see if you need to collapse the nodes and merge them into one.
I am trying to use and understand the D3 visualization library (http://mbostock.github.com/d3/), and I am looking at their force directed code and it seems they are using a quadtree to calculate the f
My application loads a collection of ~100k items (rectangles) from a map file, then builds a MX-CIF quadtree as an index for fast lookup.The quadtree is built at startup and its contents do not change
In my 2D game, I have static and dynamic objects. There can be multiple cameras. My problem: Determine objects that intersect with the current camera\'s view rectangle.
I need to know if this algorithm is a known one: void getMatches(IpVec &ipts1, IpVec &ipts2, IpPairVec &matches, float ratio) {
All, There are a few examples on implementing a quadtree using Python but my question is, does anyone know of a class written in pure python as in a single .py file that I can easily include in my pr
Hi I have a problem work whit very big gpx tracks for Android. I would like to add small parts of track to qua开发者_JS百科dtree, and only this small parts draw to the display. My real problem is how
I have a very large point cloud (> 100000 points) that I\'d like to detect planar arrangements in. I decided to use an octree to break the points into very small planar clusters and then merge neighbo
I\'ve read so many articles, but none seem to answer this question. Or maybe I\'m just not understanding. I\'m attempting to build a quadtree so that it can represent an image. The leaf nodes are to h
Does anyone know the best way to perform Quadtree decomposition on a non square image? I keep getting lines appearing across my image which 开发者_如何学运维is drawn using a Quadtree.The simplest thin
