B-spline

A B-spline is a mathematical tool used to create smooth, flexible curves through a set of points. Think of it as a way to draw a continuous, flowing line that smoothly passes near or through specific locations, while allowing control points to influence its shape. B-splines are widely used in computer graphics, design, and engineering because they provide precise control over complex shapes, ensuring smoothness and accuracy. Essentially, they help digitally sculpt curves that look natural and professional, making them essential in creating everything from animated characters to manufacturing parts.
