Polygons with Double Coordinates
double, java, polygon
Solution
You can do this with Path2D.Double:
Path2D path = new Path2D.Double();
path.moveTo(valoresX[0], valoresY[0]);
for(int i = 1; i < valoresX.length; ++i) {
path.lineTo(valoresX[i], valoresY[i]);
}
path.closePath();

Problem
I have some questions about Polygons with points of Double type... What I have to do, is given points, create the polygon, and then, test if 1 concrete point is inside the polygon or not. so I kwnow that in Java there's a class, called Polygon, and is used like that: (triangle) ``` int valoresX[] = { 100, 150, 200 }; int valoresY[] = { 100, 200, 100 }; int n = valoresX.length; Polygon city= new Polygon(valoresX,valoresY,n); ``` But my "polygons" has to be of "Double" type, not "int" (easy example) ``` Double valoresX[] = { 1000.10, 150.10, 200.10 }; Double valoresY[] = { 100.10, 200.10, 100.10 }; ``` In my project i dont really need to paint it on an applet or similar, I just need to calculate if the point is inside or not. So my question is: Is any way to do polygons with double coordenates , that allow to calcultate if the point(double) is inside the polygon or not? Thanks for all!!! Shudy
