public static function CalculateFrustumPlanes(camera: Camera): Plane[];
public static Plane[] CalculateFrustumPlanes(Camera camera);

Description

Calculates frustum planes.

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

Ordering: [0] = Left, [1] = Right, [2] = Down, [3] = Up, [4] = Near, [5] = Far

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); } }

public static function CalculateFrustumPlanes(worldToProjectionMatrix: Matrix4x4): Plane[];
public static Plane[] CalculateFrustumPlanes(Matrix4x4 worldToProjectionMatrix);

Description

Calculates frustum planes.

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