Given two overlapping polygons A and B, the Polygon Merge algorithm derives a new polygon whose edges are outermost, partial edges of A and B. The algorithm has been verified to satisfy correctness criteria expressed as two point-set properties. We have constructed a rigorous proof using the ...
Die beiden Vereinfachungsalgorithmen sind POINT_REMOVE und BEND_SIMPLIFY. Weitere Informationen zum Werkzeug "Linie oder Polygon vereinfachen" Polygonerstellung und Konfliktsuche vereinfachen Die Polygonerstellung zu vereinfachen bedeutet, dass Details in den Grenzen von Gebäuden reduziert werden, wobei...
Two decimation algorithms are available: a vertex removal decimation algorithm that utilizes accumulated error measurement an edge squeezing decimation algorithm that utilizes a fast quadric error distance to choose optimal points. Ray Firing The process of ray firing is useful for selection, position dep...
Today, based on the article Triangulation of polygon from a book "Computational Geometry: Algorithms and applications", I implemented an algorithm of triangulation of any polygon without self intersections (non-convex polygons too) in C++. Why it was needed for me? Probably, you know about a ...
Martinez-Rueda polygon clipping algorithm, does boolean operation on polygons (multipolygons, polygons with holes etc): intersection, union, difference, xor - w8r/martinez
This library depends on Martinez polygon clipping algorithm, and combined with it weighs ~14kb.InstallNode$ npm install polygon-offsetBrowserifyvar Offset = require('polygon-offset');BrowserUse// if the first point repeats(for instance GeoJSON) - // the output will have it as well var points ...

F. Martinez paper另一个关键观点是的,如果我们使用它Bentley-Ottmann algorithm检测线之间的交叉点,然后我们可以利用同时,计算线段填写注释 这是一个非常聪明的观察……但这意味着我们需要使我们的交叉检测相当复杂. 使用该技术的另一个优点是,它比依次测试每个边缘快得多,特别是随着线段数的增加. ...
Abstract: This document describes a C library implementation of a new polygon clipping algorithm. The techniques used are descended from Vatti's polygon clipping method [1]. Subject and clip polygons may be convex or concave, self-intersecting, contain holes, or be comprised of several disjoint ...
To remove triangles from the 3D mesh, the Merge Initial Coordinates algorithm runs through each triangle apex in the mesh and removes it from the data set if that apex is not the chosen persistent point for the octel under consideration. The resulting data set defines a mesh that has exactly...
