The B-spline curve is one of the most famous curves in computer graphics, computational geometry and CAGD. Developing more convenient techniques for designing and modifying B-spline curves is an important problem, and is also an important research issue. In this study, the shape modification of B-spline curves by geometric constraints is presented. A new method based on changing the control points of the curves via constrained optimization is proposed. To satisfy the given constraints, the shape of the curves is optimally modified with adjusting control points of the original B-spline curves. Finally, numerical examples are also given.
