Java FX - Generating Regular Polygon Vertices
Use the following function to create an array of Double values to use with the class javafx.scene.shape.Polygon.
static Double[] makeReglarPolyPoints(int numSides, int radius) {
double angleIncrement = Math.PI * 2 / numSides;
Double[] points = new Double[2* numSides];
for (int i = 0; i < numSides; i++) {
double px = radius * Math.cos(angleIncrement * i);
double py = radius * Math.sin(angleIncrement * i);
points[2*i] = px;
points[2*i+1] = py;
}
return points;
}
