 ## Jupyter Notebooks
-- [shape.ipynb](shape.ipynb): This notebook implements Polygon and Polyhedron class. You can use it to plot the area that you can clip through a slope.
-- [wall.ipynb](wall.ipynb): This notebook gives a demonstration to read collision data from Dolphin and draw wall hitboxs with the shape library made by sup39.
-
-- [shape.ipynb](shape.ipynb): 多角形と多面体のクラスを実装したJupyter Notebookです。これを使って斜面をすり抜ける範囲を描画することができます。
-- [wall.ipynb](wall.ipynb): Dolphinから壁のデータを取得し、サポミクが実装した図形のライブラリを使って壁の判定を描画する方法を紹介します。
