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

Description

Calculates frustum planes.

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

See Also: Plane, GeometryUtility.TestPlanesAABB.
	// Creates 6 planes that represent the camera frustum.
