1.實作:畫愛心

Processing heart curve

Part 1

void setup() {

  size(500, 500);

}

void draw() {

  for (float theta=0; theta<frameCount/100.0; theta+=0.01) {//PI*2 is better

    float r=1-sin(theta), r2=1-sin(theta+0.01);

    float x=r*cos(theta), y=r*sin(theta);

    float x2=r2*cos(theta), y2=r2*sin(theta);

    line(250+100*x, 250-100*y, 250+100*x2, 250-100*y2);

  }

}

Part 2

void setup() {

  size(400, 400);

  noStroke();

}

void draw () {

  for (float x=-2; x<=2; x+=0.01) {

    for (float y=-2; y<=2; y+=0.01) {

      if ((x*x+y*y-1)*(x*x+y*y-1)*(x*x+y*y-1)-x*x*y*y*y<0)

      fill(255, 0, 0);

      else

      fill(255);

      rect(200+x*100, 200-y*100, 10, 10);

    }

  }

}

Part 3

void setup() {

  size(400, 400);

  noStroke();

}

void draw () {

  for (float x=-2; x<=2; x+=0.01) {

    for (float y=-2; y<=2; y+=0.01) {

      if ((x*x+y*y-1)*(x*x+y*y-1)*(x*x+y*y-1)-x*x*y*y*y>0)

      fill(255, 0, 0);

      else

      fill(255);

      rect(200+x*100, 200-y*100, 10, 10);

    }

  }

}

sin & cos

void setup(){

  size(400,400);

}

void draw(){

  float angle= -radians(frameCount)/3;

  rect(0,0,200,200);

  stroke(0,0,255);

  ellipse(100,100,100,100);

  line(100,100,100+cos(angle)*50,100+sin(angle)*50);

  

  //rect(200,0,200,200);

  ellipse(200+abs(angle)*30,100+sin(angle)*50,10,10);

  

  ellipse(100+cos(angle)*50,200+abs(angle)*30,10,10);

}
