変数値となる行は 冒頭に出す
"代表_球体半径" = 0.01
main_sphere_radius = "代表_球体半径"
このような形にする
代表_球体半径 の初期位置は
変数値 (-1,0,0) と (1,0,0)の中間位置とする
代表_球体を 初期位置から
(5,0,0)へ動かす そこから
(-5,0,0)へ動かす そこから
(0,0,0)へ動かすアニメを作る
キーフレーム設定とかも忘れずに

「球体x」方向は 経由地を
0,0,0 to 3,0,0 to 0,0,0 to 3,0,0 to 0,0,0
「球体ｘｙ」方向は 経由地を
0,0,0 to 3,-3,0 to 0,6,0 to 3,9,0 to 0,0,0
「球体ｘｙｚ」方向は 経由地を
0,0,0 to 3,-3,-3 to 0,-6,-6 to 3,-9,-0 to 0,0,0
「球体ｘ」が 経由地それぞれを通過するフレーム時に
その他の球体が それぞれの経由地を同時通過する
だから 経由地と経由地の距離から 表示移動速度を計算して
描画する
