What is a NURBS sphere?
NURBS Sphere Adds a generic sphere constructed by revolving a grid of control points about an axis.
What are NURBS good at?
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.
How do you make NURBS?
Create NURBS primitives using the Create menu
- Select Create > NURBS Primitives, then select the primitive’s option box from the list of primitives. For example, Sphere > or Cube > .
- In the primitive options window, change the attributes of the NURBS primitive.
- Click Create.
Does Blender have NURBS?
Blender internally treats NURBS surfaces and NURBS curves completely differently. There are several attributes that separate them but the most important is that a NURBS curve has a single interpolation axis (U) and a NURBS surface has two interpolation axes (U and V).
Why are NURBS used?
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 the difference between NURBS and 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.
What is a 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 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.
How do you use NURBS?
You can use NURBS in two ways:
- Construct 3D models from NURBS primitives.
- Construct NURBS curves that define the basic outline of the 3D form you want to construct, then use the curves as a basis for constructing NURBS surfaces.
