精度タイプ
説明
現在、Shader Graph には 2 つの Precision (精度) タイプが提供されています。精度モード のリストにあるオプションを使用して各ノードの Precision Type (精度タイプ) を定義します。

Half |
半精度の浮動小数点値です。通常は 16 ビット (–60000 から +60000 の範囲で、およそ小数点以下 3 桁の精度)。 精度 Half は、短いベベクトル、方向、オブジェクト空間位置、HDR カラーに役立ちます。 |
Float |
最も高い精度の浮動小数点値です。通常は 32 ビット (通常のプログラミング言語における Float と全く同じ) です。 完全な Float 精度は、ワールド空間位置やテクスチャ座標、また三角法、累乗、べき数などの複雑な関数を含むスカラー計算に役立ちます。 |
