 * @param normal   {@link Vector3} The normal vector of the plane the spiral is in. This is assumed to be
 *                 orthogonal to the vector formed from the start to the origin.
 * @param spiralIn {@code boolean} True if the spiral should move from the staring point in. False to move from starting point out.
