# Nonuniform rational B-spline (NURBS)

A NURBS curve is a mathematical model used in computer graphics for generating and representing curves. NURBS curves are defined by a set of control points and a weighting function. The control points define the shape of the curve and the weighting function defines how the curve interpolates between the control points.

NURBS curves can be used to represent a wide variety of shapes, including straight lines, circles, ellipses, and freeform curves. They are commonly used in computer-aided design (CAD) and computer-aided manufacturing (CAM) applications.

NURBS curves are also sometimes used in computer graphics to generate smooth animations. For example, a NURBS curve can be used to interpolate between two keyframes in an animation. This can give the animation a more natural look, as opposed to using linear interpolation.

### What is Nurb?

In mathematics, a NURB is a type of mathematical model used to describe curves or surfaces. NURBs are commonly used in computer graphics and CAD/CAM applications.

A NURB curve is defined by a set of control points, weights, and knots. The control points define the shape of the curve and the weights determine how strongly each control point influences the shape of the curve. The knots define the placement of the control points on the curve.

#### What is NURBS in CAD?

NURBS is an acronym for Non-Uniform Rational B-Splines. They are a mathematical model used to create smooth curves and surfaces. CAD software typically uses NURBS to represent curves and surfaces.

NURBS are defined by a set of control points, weights, and knots. The control points define the shape of the curve or surface, the weights control the amount of influence each control point has, and the knots define how the control points are connected. What is the easiest way to change the geometry of a NURBS curve? There is no easy way to change the geometry of a NURBS curve. The only way to change the geometry of a NURBS curve is to change the control points that define the curve.

### What is the difference between NURBS and mesh?

NURBS (Non-Uniform Rational B-Splines) are mathematical functions that can be used to describe any shape, regardless of how complex it may be. They are commonly used in computer graphics and CAD/CAM applications.

Mesh is a collection of vertices, edges, and faces that define the shape of an object. A mesh can be thought of as a net that covers the surface of an object. Meshes are commonly used in 3D printing and computer graphics.

What is the difference between Bezier curve and B-spline curve? Bezier curves and B-spline curves are both types of curves that can be used to approximate a set of data points. Bezier curves are defined by a set of control points, while B-spline curves are defined by a set of control points and a set of knots. Knots are points in the curve that define how the curve is interpolated between the control points.
