GeometryUtility.TestPlanesAABB

Description

Возвращает true, если границы находятся внутри какой-либо плоскости массива.

Вернет true, если ограничивающий прямоугольник находится внутри плоскостей или пересекает любую из них.

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.
