public static Plane[] CalculateFrustumPlanes (Camera camera);

説明

錐台平面を計算します

This function takes given camera's view frustum and returns six planes that form it.

順番: [0] = Left, [1] = Right, [2] = Down, [3] = Up, [4] = Near, [5] = Far

説明

錐台平面を計算します

この関数では、カメラの View や投影マトリクスを指定するとそれを構成する六つの平面を返します。
