花を形成する楕円を成長させるループを誰かが手伝ってくれませんか。花びらとして機能する5つの楕円と、1つの中央の花の楕円があります。

Stem myStem;
Circle circles[];

float scaleFactor=0.5;

void setup() {


size(floor(400*scaleFactor), floor(800*scaleFactor));
myStem = new Stem(200,800);
//mpoved this to setup, no need to recreate each frame
circles = new Circle[6];
circles[0]  = new Circle(0, -40, 50, 50);
circles[1]  = new Circle(0, -40, 50, 50);
circles[2]  = new Circle(0, -40, 50, 50);
circles[3]  = new Circle(0, -40, 50, 50);
circles[4]  = new Circle(0, -40, 50, 50);
circles[5]  = new Circle(0, 0, 50, 50);
// also smooth only needs to be called once
// unless ther is a noSmooth() somewhere
// smooth();
}

void draw() {

  float grow = 0;
  //translate(myStem.initalloX, myStem.initalloY);  
  myStem.drawStem();
  //set centre point
  if (frameCount>grow) {
    translate(myStem.initalloX, ((frameCount>250)?myStem.initalloY-      500:myStem.initalloY-(2*frameCount)));

    c1 = tc1;
    c2 = tc2;
    c3 = tc3;
    c4 = tc4;
   }
 }

これはプログラムの関数であり、Processingで記述されています。ヘルプ/入力を事前に感謝します！

_hi theolc、あなたの成長する花のために、私はこのようなことをします、あなたにとって非常に簡単なスタートです;）。それが役立つかどうかを確認してください。この場合、回転よりも制御が簡単であると思われるため、三角法を使用することにしました。それをチェックしてください（マウスをクリックして拡大/クリックして任意のキーを押したまま縮小）：
