Camera.cullingMatrix

Description

Sets a custom matrix for the camera to use for all culling queries.

Это будет продолжаться до тех пор, как вы не вызовете ResetProjectionMatrix.

A custom culling matrix can be useful in situations where multiple cameras must be culled identically in order to render effects such as reflections.

public class ExampleClass : MonoBehaviour {
	
	Camera cullingCamera;
	
	void Awake () {
	    cullingCamera = gameObject.AddComponent<Camera>();		
	    SetMainCameraCustomCullingMatrix (new Vector3 (10.0f, 10.0f, 10.0f), Vector3.zero);
	}
	
	void SetMainCameraCustomCullingMatrix (Vector3 cameraPosition, Vector3 lookAtPosition) {
	    transform.position = cameraPosition;
	    transform.LookAt (lookAtPosition);
	    Camera.main.cullingMatrix = cullingCamera.projectionMatrix * cullingCamera.worldToCameraMatrix;
	}
	
	void ResetMainCameraCullingMatrix () {	
	    Camera.main.ResetCullingMatrix();
