Lissajous Patterns

• • Read about Lissajous patterns here: http://en.wikipedia.org/wiki/Lissajous_curve

  • Ask Teresa if you don’t understand

  • Here’s a program I wrote:

float angle = 0;

float x = 0;

float y = 0;

void setup()

{

size(400,400);

background(#37458B);

stroke(255);

strokeWeight(2);

stroke(#F9FF4D);

}

void draw()

{

x = 200 + 100*sin(radians(angle));

y = 200 + 100*sin(radians(angle) + radians(40));

point(x,y);

angle = angle+2;

}

• • Can you figure out what simple change I made to draw this instead?
