-提示コードですが正射形行列を使って2Dでフォンシェーディングを行いその後bloomを行いたのですが正射形で実装しましたがライティングされません。`Draw_setBloom()`関数部ですが`.frag`シェーダーの何が間違えているのでしょうか
+提示コードですがbloom効果を実装したいのですが画面に何も表示されず困っています。bloomの描画手順ですが以下の説明で正しいのでしょうか？
-##### 調査したこと、調べたこと
+##### 描画手順
-描画は正射形行列です。
-カメラの初期座標は0,0,10です。向きは-1です。
-スプライトの座標は0,0です。
-スプライトの頂点の法線向きはすべて0,0,1 です。
-シェーダーでは二次元の座標を渡して三次元目は-1にしています。
-全てのシェーダーに頂点情報を設定
-他の物が影響している可能性があるためループ部を短縮化
-シェーダーを書き写しライト描画のfor文を消して一つのライトに変更
+1,シーンを描画して一つは普通の描画結果で、二つ目は輝度を取得するカラーバッファを作る
+2,bloomブラーを付ける
-Draw_setBloom()関数でシーンを描画してカラーバッファを作成して輝度のカラーバッファ作成
+3,ブラーを付けたカラーバッファを最後に描画するカラーバッファにつける。
-Draw_setBlur()関数でbloomを描画
-Draw_Final()関数でカラーバッファを描画

-##### 現状
-描画は正射形行列です。
-シェーダーでは二次元の座標を渡して三次元目は-1にしています。
-他の物が影響している可能性があるためループ部を短縮化
-シェーダーを書き写しライト描画のfor文を消して一つのライトに変更
-Draw_setBloom()関数でシーンを描画してカラーバッファを作成して輝度のカラーバッファ作成
-Draw_setBlur()関数でbloomを描画
-Draw_Final()関数でカラーバッファを描画

 ##### 現状
+描画は正射形行列です。
+シェーダーでは二次元の座標を渡して三次元目は-1にしています。
 他の物が影響している可能性があるためループ部を短縮化
 シェーダーを書き写しライト描画のfor文を消して一つのライトに変更
