public static bool TestPlanesAABB (Plane[] planes, Bounds bounds);

描述

如果边界位于该平面数组内,则返回 true。

如果包围盒位于这些平面内,或者与其中任何平面相交,则将返回 true。

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.
The test is conservative and can give false positive results. A bounding box can intersect the planes outside of the frustum because the planes are infinite and extend beyond the frustum volume. A typical false positive result is produced by a big bounding box near the frustum edge or corner.
