Curve representation refers to the methods used to describe and visualize curves in mathematics and computer graphics. Common techniques include parametric equations, where a curve is defined using one or more parameters, and implicit equations, which define a curve as the set of points satisfying a specific equation. In computer graphics, curve representation is essential for modeling shapes and animations. Techniques like Bezier curves and B-splines allow for smooth and flexible designs, making them popular in applications such as 3D modeling and animation. These representations help artists and engineers create complex forms with precision.
