GeometryUtility.CalculateFrustumPlanes

Description

錐台平面を計算します

この関数では、カメラの View Frustumを指定するとそれを構成する六つの平面 を返します。 See Also: Plane, GeometryUtility.TestPlanesAABB.

	// Creates 6 planes that represent the camera frustum.

	private var cam : Camera;
	private var planes : Plane[];

	function Start() {
		cam = Camera.main;
		planes = GeometryUtility.CalculateFrustumPlanes(cam);

		for(var i : int = 0; i < planes.Length; i++) {
			var p : GameObject = GameObject.CreatePrimitive(PrimitiveType.Plane);
			p.name = "Plane " + i.ToString();
			p.transform.position = -planes[i].normal * planes[i].distance;
			p.transform.rotation = Quaternion.FromToRotation(Vector3.up, planes[i].normal);
		}
	}
