Algorithm 1

Fast rectangle-packing algorithm.
For each rectangle {
 For each edge {//the order of processing edges.
  Calculate one or two candidate positions to place on ;
  For(each candidate position dt) {
   If (dt satisfies both conditions 1 and (2) {
    T = dt; goto PlaceNow;//T is the final position of.
    }
   If (dt satisfies only condition 1){
    Calculate bB + gG; //Section 4.3 describes the calculation of bB + gG.
    If (bB + gG is less than the previous candidate positions){
     T = dt;
   }
  }
 }//end of for (dt).
}//end of for.
PlaceNow:
 Place at T; Modify M;//the modification of the mesh.
}//end of for.
