コードは波の形と色を決める部分に大きく分けられる。

  • 形
    • noise
    • octave(重ね合わせ)
    • choppy(鋭さ)
  • 色
    • fresnel的な屈折光と反射光の合成(拡散光で良い)
    • 白いギラギラした照り返しを表現するspecular
  • 深度とカメラ距離の加味（浅さと深さで明るさ調整）

I'd like to share how we can exchange data between open3d.Image and numpy. I think this would be helpful for python beginners like me X)
