■使用ソフト
・Visual Studio Community 2019
■言語
・C/C++
■Windows SDK バージョン
・10.0.17763.0
※Windows SDK バージョンの変更方法
■手順
１．以下をベースにコード変更する。
【C++】 DirectX11 - 四角形の描画（インデックスバッファ）
２．以下の6つのファイルを作成してビルドを行う。
（１）Main.h //前回から変更なし
（２）Main.cpp //前回から変更なし
（３）DirectX.h //前回から変更なし
（４）DirectX.cpp
（５）VertexShader.hlsl //前回から変更なし
（６）PixelShader.hlsl //前回から変更なし
（１）Main.h
