Computer-aided geometric design


Computer-aided geometric design (CAGD), also known as geometric modeling, is a branch of computational geometry. It deals with the construction and representation of free-form curves, surfaces, or volumes.[1]
Computera-aided geometric design (CAGD) studies especially the construction and manipulation of curves and surfaces given by a set of points using polynomial, rational, piecewise polynomial, or piecewise rational methods. This branch is closely related to several other branches, such as geometric modeling (for example, Non-Uniform Rational B-Spline (NURBS) objects represent the fundamental structures of modern computer systems used in the aircraft and car industry, such as CATIA V5) or data fitting (interpolation, approximation of a set of points).[2]
Fields of application
Architectural Freeform Design

Smart Geometry | Architecture in a Parametric Age |
Geometric problems originating in architecture can lead to interesting research and results in geometry processing, computer-aided geometric design, and discrete differential geometry.[3]
