Hello everyone, Dr. wood told me that I can adapting his example to force cubic spline to pass through certain point. I still have no idea how to achieve this.

Abstract: An approach to constrained timeefficient and smooth cubic spline trajectory generation is presented. A function to combine the minimisation of travelling time with smoothness of the robot trajectories is proposed. Cubic splines are used to describe the joint trajectories which satisfy constraints on velocity, acceleration and jerk.

In this paper, a rational cubic interpolant spline with linear denominator has been constructed, and it is used to constrain interpolation curves to be bounded in the given region. Necessary and sufficient conditions for the interpolant to satisfy the constraint have been developed.
