|---|---|
| bool |
Remarks
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.
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.

Examples
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"); } }}
