+# RotBlur_M
+AviUtl拡張編集用、GPUを使用した高速回転ブラースクリプト
+
+## 導入方法
+1. karoterra氏の[GLShaderKit](https://github.com/karoterra/aviutl-GLShaderKit)を導入
+2. exedit.aufと同一ディレクトリにあるscriptフォルダ内、またはそのフォルダの1階層下に`RotBlur_M.anm`,`RotBlur_M.frag`,`RotBlur_M.vert`を配置
+
+## パラメータ説明
+### X
+回転の中心となるX座標
+### Y
+回転の中心となるY座標
+### amount
+回転ブラーの角度
+### r_pos
+基準座標
+### keep_size
+サイズを保持したままエフェクトをかけるか
+### quality
+描画回数 / 2  
+数字が大きければ大きいほどブラーとしての精度は向上するが、重くなります。
+### reload
+シェーダーを都度リロードするか  
+主にデバッグ用なので、オフのままを推奨
+### PI
+トラックバーのパラメータインジェクション用
