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

Description

Returns true if bounds are inside the plane array.

Will return true if the bounding box is inside the planes or intersects any of the planes.

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.

using UnityEngine;

public class Example : MonoBehaviour { // Detects manually if obj is being seen by the main camera

GameObject obj; Collider objCollider;

Camera cam; Plane[] planes;

void Start() { cam = Camera.main; planes = GeometryUtility.CalculateFrustumPlanes(cam); objCollider = GetComponent<Collider>(); }

void Update() { if (GeometryUtility.TestPlanesAABB(planes, objCollider.bounds)) { Debug.Log(obj.name + " has been detected!"); } else { Debug.Log("Nothing has been detected"); } } }
