Every discipline has a purpose. Ethics, according to Adela Cortina, helps us commit to a happy and good life—a life:

Core Concepts of CAD Modeling and Geometric Representation

Bezier Surfaces

A Bezier surface is a parametric surface used in computer-aided design for modeling smooth and curved shapes. It is an extension of the Bezier curve into two parameters, generally represented by u and v. A Bezier surface is defined by a grid of control points that influence the shape of the surface. The surface does not necessarily pass through all control points, but its shape is controlled by them.

Bezier surfaces use Bernstein polynomials for mathematical representation. They provide
