Using a turtle graphic and recursive functions is relatively an easy way to generate trees or plants in a computer.

This is very simple algorithm like this:

void KwTree_001(K3DTurtle kt,float w,int ct)
{
  if(ct<0) return;
  float w1=w/4.0, w2=w1*3.;
  kt.Move(w1);    // Draw line only 1/4 length.
  K3DTurtle kt2;
  int i,n=4;
  float a=30, b=360/n;
  for(i=0;i<n;i++){
    kt2=kt; kt2.TurnUp(a);
    // Recursive Call. Change the length slightly by random.
    KwTree_001(kt2,w2*(1.0+0.05*(rand()%10-5)),ct-1);
    kt.RotateRight(b*(i+1));
  }
}

KwTree_001(k3t,w,4);  // Main Call

Used iteration to grow trunk, and used recursion to generate branch.

I'm planning to use two important characteristics:

• Both Recursive Call and Iteration to simulate growing.
  
• Genetic information and its realization mechanisms to simulate a generation of body.
