So I'm trying to draw a curve that has a taper profile like this : y=
Since I'm using awt.Graphics2D , I only have the ability to draw shapes .
One way to draw curves is to draw curves is use use B´ezier curves. Is there a way convert this or a awt trick I'm not familiar with ?
One option to draw a curve is point by point :
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Curve extends JPanel {
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
g2d.setColor(Color.RED);
for (int x = 1; x <= 100; x++) {
int y = getY(x);
//2g does not support drawing a point so you draw a line
g2d.drawLine(x, y, x, y);
}
}
/**
*@param x
*@return
*/
private int getY(int x) {
//change to the function you want
return 50+ (100/(1+ (3* x)));
}
public static void main(String[] args) {
Curve points = new Curve();
JFrame frame = new JFrame("Curve");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(points);
frame.setSize(350, 300);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
}
