5.4 Layering

Layering

By paying attention to the order in which you do things, you can build up complex shapes.

Some tips:

Draw the background first
Draw "cut outs" in the background colour
Cut off pieces of the shape using boxes in the background colour

Doughnut - white circle in middle

g.fillOval(10,10, 100,100);
g.setColor(Color.white);
g.fillOval(30,30,60,60);

Arc - doughnut with a rectangle cover

g.fillOval(10,10, 100,100);
g.setColor(Color.white);
g.fillOval(30,30,60,60);
g.fillRect(10,60,100,50);

Cup - build up pieces

import java.awt.*;
import java.applet.*;

public class cup extends Applet
{
public void paint (Graphics g)
{//handle, pull out middle
g.fillOval(60,10,40,40);
g.setColor(Color.white);
g.fillOval(70,20,20,20);
//curved corner
g.setColor(Color.black);
g.fillOval(30,30,20,20);
//cup, blocking in space
g.fillRect(30,10,50,30);
g.fillRect(40,30,40,20);
//saucer
g.fillRect(10,60,90,10);
}
}
