GeometryUtility.CalculateFrustumPlanes

Description

Calculates frustum planes.

This function takes given camera's view frustum and returns six planes that form it.

	// 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);
		}
	}

Description

Calculates frustum planes.

This function returns six planes of a frustum defined by given view & projection matrix.
