Question

processing pde

design two different works of recursive shapes, must incorporate pushMatrix() , popMatrix(), and ArrayList along with both mouse and key interactivities

Answer 1

int c_center = 25;
int c_petal = 30;
int petalsize = 80;
color col;

void setup(){
  fullScreen();
  background(0);
}

void draw(){
  rcol = color(random(255), random(255), random(255));
}

void mouseClicked(){
  pushMatrix();
  flower();
  translate(mouseX, mouseY);
  rotate(PI/4);
  flower();
  popMatrix();
}

void flower(){
  //left petal
  make_petal(mouseX - (petalsize - c_petal), mouseY, petalsize, c_petal);
  //right petal
  make_petal(mouseX + (petalsize - c_petal), mouseY, petalsize, c_petal);
  //top petal
  make_petal(mouseX, mouseY - (petalsize - c_petal), c_petal, petalsize);
  //bottom petal
  make_petal(mouseX, mouseY + (petalsize - c_petal), c_petal, petalsize);
  //flower center
  fill(random(255), random(255), random(255));
  ellipse(mouseX, mouseY, c_center, c_center);
}

void make_petal(int w, int x, int y, int z){
  fill(col);
  ellipse(w, x, y, z);
}
