畫會動的眼睛眼球

程式碼:

void setup(){

  size(120,120);

}

void draw(){

  float t =frameCount/180.0*PI;

  background(0);

  fill(255);

  ellipse(40,50, 33,33);

  ellipse(120-40,50,33,33);

  fill(0);

  ellipse(40+15*cos(t),50+15*sin(t),5,5);

  ellipse(123-40+15*cos(t),50+15*sin(t),5,5);

}

用滑鼠控制眼球 做出鬥雞眼

程式碼:

void setup(){

  size(120,120);

}

void draw(){

  //float t =frameCount/180.0*PI;

  background(0);

  fill(255);

  ellipse(40,50, 33,33);

  ellipse(120-40,50,33,33);

  fill(0);

  float t=atan2(mouseY-50,mouseX-45);

  ellipse(40+15*cos(t),50+15*sin(t),5,5);

  t=atan2(mouseY-50,mouseX-(120-40));

  ellipse(123-40+15*cos(t),50+15*sin(t),5,5);

} 

雙螺旋轉動
程式碼:

void setup(){

  size(600,600);

}

void draw(){

  //float t =frameCount/180.0*PI;

  background(0);

  float t=frameCount/100.0;

  for(float f=0; f<PI; f+=0.1){

    rect(200+150*cos(f+t),f*100,30,30);

    rect(200+150*cos(f+t+PI),f*100,30,30);

  }
