What type of point follows a smooth curve on a path?

A smooth point is characterized by its ability to facilitate the seamless flow of a curve, allowing for a continuous transition from one direction to another without abrupt changes. In graphical design and vector graphics software, smooth points serve as anchor points that dictate the curvature of lines or paths. Unlike corner points, which create sharp angles, smooth points ensure that the curve remains fluid and visually appealing.

When you manipulate a smooth point, the changes affect the surrounding control handles, allowing for a cohesive and elegant deformation of the curve. This is essential for creating shapes that require gentle transitions, such as organic forms or flowing designs. The presence of smooth points in design is crucial for maintaining aesthetic quality and ensuring that the viewer's eye travels seamlessly along the intended path.

In contrast, constrain points and corner points serve different functions related to the rigidity and angularity of shapes, while anchor points can refer to both smooth and corner points without specifying the nature of the curve. Therefore, the clarity of the smooth point's purpose in maintaining a gentle curvature makes it the correct answer.
