## What is NURBS modeling in Maya?

Non-Uniform Rational B-Splines (NURBS) provide a 3D modeling framework based on geometric primitives and drawn curves. You can use NURBS in two ways: Construct 3D models from NURBS primitives. Primitives are simple 3D objects created in the shape of common geometric forms such as cubes, spheres, cones, and so on.

### What is NURBS modeling used for?

Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces. It offers great flexibility and precision for handling both analytic (defined by common mathematical formulae) and modeled shapes.

**What is NURBS in detail?**

NURBS, Non-Uniform Rational B-Splines, are mathematical representations of 3D geometry that can accurately describe any shape from a simple 2D line, circle, arc, or curve to the most complex 3D organic free-form surface or solid.

**What is the difference between NURBS and polygon modeling in Maya?**

For polygon modeling it calculates polygons, which are flat planes that comprise a 3D shape (the way that a cube is made out of 6 squares for example). NURBS calculates the mesh as splines between points, which can make curves out of a single section of geometry.

## How do you make a NURBS curve?

Creating NURBS curves

- Draw NURBS curves.
- Create a curve from a surface edge, isoparm, or curve-on-surface.
- Create a Bezier curve.
- Create arcs.
- Create a fillet curve between two existing curves.
- Create a degree 3 curve to match degree 1 (scan) data.
- Import vector data as curves or generate polygonal surfaces.

### Is NURBS a mesh?

A NURBS model consists of points connected by curves. A polygon mesh consists of thousands or millions of small triangles. CAD surface models are usually created using NURBS surfaces, while 3D scans are typically exported as a polygon mesh.

## Should I use NURBS for car modeling?

The solution isn’t always to use NURBS, but working with curves and surfaces offers up a lot of benefits, especially when modeling things like cars. In this tutorial Modeler, Alex Cheparev shows how to work with NURBS curves and surfaces to build a unique looking Messerschmitt KR200 car.

### What is NURBS in AutoCAD?

NURBS (Non-Uniform Rational B-Splines) is a unique workflow for modelers that sort of rides the line between polygon modeling and solid modeling. “We’ll create body panels from simple curves and NURBS operations,” Cheparev says about the techniques used in the tutorial.

**What are curves in Maya and Rhino?**

Bend lines created in Maya and Rhino are called CURVES, that are based on Bezier Curves and are used as the basis for NURBS and Polygon modeling within Maya or only as basis for NURBS modelling in Rhino. The way the curves are defined makes is possible to draw straight lines and smooth curves.

**Where can I find the NURBS curve drawing tools?**

The curve drawing tools are found in the Create menu. The options for creating and editing NURBS curves and NURBS surfaces are found in the Modeling menu set. You can also find NURBS options on the Curves/Surfaces shelf. Post a question.
