line-intersection

问题 I have set of line segments (not lines) , (A1, B1) , (A2, B2) , (A3, B3) , where A , B are ending points of the line segment. Each A and B has (x,y) coordinates. QUESTION: I need to know the shortest distance between point O and line segments as shown in the shown figure implemented in line of codes. The code I can really understand is either pseudo-code or Python. CODE: I tried to solve the problem with this code, unfortunately, it does not work properly. def dist(A, B, O): A_ = complex(*A)

问题 Given N lines ( either horizontal or vertical ), I need to find total intersection of these line segments as well as intersections per line. My code is as follows : using namespace std; #define x second #define y first #define MAX 10000 typedef pair<int,int >point; struct event { point p1,p2; int type; event() {}; event(point p1,point p2, int type) : p1(p1), p2(p2),type(type) {}; //initialization of event }; int n,e; event events[MAX]; bool compare(event a, event b) { return a.p1.x<b.p1.x; }

问题 I have created a function to calculate the intersection point of two line segment . Unfortunantly the code below dosen't work if one of the segment is verticale public static Point intersection(Segment s1, Segment s2) { double x1 = s1.getP1().getX(); double y1 = s1.getP1().getY() ; double x2 = s1.getP2().getX(); double y2 = s1.getP2().getY() ; double x3 = s2.getP1().getX(); double y3 = s2.getP1().getY(); double x4 = s2.getP2().getX(); double y4 = s2.getP2().getY(); double d = (x1 - x2) * (y3

问题 Is there any existing Bentley-Ottmann Algorithm Implementation/library in C# or Java? 回答1: Here is a Java implementation of the Bentley-Ottman algorithm 回答2: Here is at least a C++ implementation (including description): http://softsurfer.com/Archive/algorithm_0108/algorithm_0108.htm 来源： https://stackoverflow.com/questions/8113263/bentley-ottmann-algorithm-implementation
