How do you model with NURBS in Maya?

NURBS Modeling

1. You can draw curves by placing control vertices, or edit points. The curve drawing tools are found in the Create menu.
2. The options for creating and editing NURBS curves and NURBS surfaces are found in the Modeling menu set.
3. You can also find NURBS options on the Curves/Surfaces shelf.

How do you make NURBS curves?

To create a NURBS curve by control point:

1. Click the NURBS Curve tool from the 3D Modeling tool set, and click the Control Point mode.
2. Click to set the first point on the curve.
3. Click to set the point that the curve pulls toward but does not touch.
4. Double-click to set the end point of the curve.

What are NURBS good for?

NURBS are useful for constructing many types of organic 3D forms because of the smooth and minimal nature of the curves they use to construct surfaces. NURBS surface types are widely used in the fields of animation, games, scientific visualization, and industrial design.

What is the difference between NURBS and polygons?

The difference between NURBS and Polygons is NURBS use curves and splines, whereas Polygons use flat and straight lines and vertices to create a mesh. NURBS are most commonly used in engineering models where accuracy is paramount. Polygons create solid planes and shapes by drawing lines between specific vertices.

What is Nurb surface?

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 spline modeling?

Spline modeling is used primarily for the creation of hard objects, like cars, buildings, and furniture. Splines are extremely useful when creating these objects, which may be a combination of angular and curved shapes. When creating a 3D scene that requires curved shapes, spline modeling should be your first choice.

What is Nurb modeling?

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.

How do you extrude NURBS in Maya?

Sweep a profile curve along a path curve

1. Select the profile curve or curves. Then select the path curve.
2. Select NURBS > Extrude.
3. Select the extrude node and choose the Show Manipulators tool to manipulate the extrude. Tip: If the path curve changes direction abruptly, the cross section may twist around the path.

What is the difference between mesh and NURBS?

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.

What is the difference between subs and NURBS?

Sub-D modeling is great at producing and modifying complex freeform / organic shapes with smooth surfaces. NURBS modeling is good at combining shapes via. Boolean and Feature operations as well as refining shapes with operations like filleting, blending and face editing.
