version 1.0.0.0 (11 KB) by
Finds the intersection points between two arbitrary polygons.

Updated 16 Feb 2007

General

This file is based on the Curve Intersect function by Duane Hanselman. It extends the scope of the function to handle arbitrary lines / polygons, which may also have vertical segments or segments with non-increasing x-values.

Description
Calculate the intersection points of two 2D-lines / polygons.

Usage
[X,Y]=CURVEINTERSECT(H1,H2) or [X,Y]=CURVEINTERSECT([H1 H2]) or
[X,Y]=CURVEINTERSECT(X1,Y1,X2,Y2) or
-> (H1,H2) handles to line objects
-> (Xi,Yi) coordinates of lines
-> (X,Y) coordinates of intersection

Example
x1=rand(10,1); y1=rand(10,1); x2=rand(10,1); y2=rand(10,1);
[x,y]=curveintersect(x1,y1,x2,y2);
plot(x1,y1,'k',x2,y2,'b',x,y,'ro')
