Introduction
NURBS VS MESH
Polygon Meshes are a collection of polygons that defines the 3D shape. A polygon is a closed 2D shape formed by vertices (points in 3d space), edges and faces. The straight line that connects two vertices is called an edge. A closed set of edges make up a face. There are exactly the same number of vertex points as edges.
NURBS stands for Non-uniform rational basis spline.
“The foundation of geometry in Rhino is NURBS, which has its roots in mathematics. Objects are defined by degree, control points, knots, and an valuation rule. Linear means degree 1, quadratic means degree 2, and so on; changing the degree of an object alters its form. Control points correspond to an object’s degree and can be edited to change the shape.”
