Assignment 2: Mathematical Images

Work in groups of two.

Ask questions to Yoshi (sunp@ucla.edu) or Kostas (kostas@ucla.edu)

Objective:

• To demonstrate the use of mathematical functions.
• To learn how to compile, run, and publish a java applet.

Description

Write the source code (with comments) for an applet that will display a 256x256 image created through string “.” as shown in the code below. Fill in the c1, c2, and c3 variables using mathematical functions to create interesting patterns (for example c1 may look like: int c1 = (int)(255. * Math.sin(Math.PI/180. * i));. )

import java.applet.*;

import java.awt.*;

public class simple extends Applet{

//*****************************************

public void paint(Graphics g){

for(int i=0; i<255; i++)

for(int j=0; j<255; j++){

int c1 =

int c2 =

int c3 =

g.setColor(new Color(c1, c2, c3));

g.drawString(".", i, j);

}

}

}

• Zip your project and source files and call it yourNames.zip (yourNames is a variable for the two partners last names).
• Send a brief e-mail to sunp@ucla.edu explaining what you did, include the URL address of where your applet is posted and attach the zipped project.

Bonus:

Excessive creativity will be kindly appreciated and highly rewarded.
