Gets the direction vectors in the central body's fixed reference frame that define the Projection's frustum. The collection contains the direction vector down the center of the projection, and the bottom left, bottom right, upper right, and upper left corner direction vectors, in that order. If no direction can be calculated, Cartesian.Zero is returned. Each vector is represented in the array as its individual components in the order x, y, z.
