GeometryUtility.TestPlanesAABB

説明

plane 配列内にバウンズがある場合は、true をします

バウンディングボックスが Plane の内側の場合か Plane のどこかで交差する場合は True が返されます。

The TestPlanesAABB function uses the Plane array to test whether a bounding box is in the frustum or not.
You can use this function with CalculateFrustrumPlanes to test whether a camera's view contains an object regardless of whether it is rendered or not.
