How can I find the point on the spline after applying with offset angle+radius?

Hi
Here is the code applying the offset:

Code:

        /// <summary>         /// Returns the position of the controller after applying an offset         /// </summary>         /// <param name="position">The controller's position</param>         /// <param name="tangent">The tangent at the controller's position</param>         /// <param name="up">The Up direction at the controller's position</param>         /// <param name="offsetAngle"><see cref="OffsetAngle"/></param>         /// <param name="offsetRadius"><see cref="OffsetRadius"/></param>         protected static Vector3 ApplyOffset(Vector3 position, Vector3 tangent, Vector3 up, float offsetAngle, float offsetRadius)         {             Quaternion offsetRotation = Quaternion.AngleAxis(offsetAngle, tangent);             return position.Addition((offsetRotation * up).Multiply(offsetRadius));         }

As you can see, the point is at a radius of offsetRadius from the point on the spline, and has an angle of offsetAngle with the spline's up vector (also called orientation) at said point.
I hope this helped
Have a nice day
