Import
NURBSSurface is an addon, and must be imported explicitly, see Installation#Addons.
import { NURBSSurface } from 'three/addons/curves/NURBSSurface.js';Constructor
new NURBSSurface( degree1 : number, degree2 : number, knots1 : Array.<number>, knots2 : Array.<number>, controlPoints : Array.<Array.<(Vector2|Vector3|Vector4)>> )
Constructs a new NURBS surface.
| degree1 |
The first NURBS degree. |
| degree2 |
The second NURBS degree. |
| knots1 |
The first knots as a flat array of numbers. |
| knots2 |
The second knots as a flat array of numbers. |
| controlPoints |
An array^2 holding control points. |
Properties
.controlPoints : Array.<Array.<(Vector2|Vector3|Vector4)>>
An array holding arrays of control points.
.degree1 : number
The first NURBS degree.
.degree2 : number
The second NURBS degree.
.knots1 : Array.<number>
The first knots as a flat array of numbers.
.knots2 : Array.<number>
The second knots as a flat array of numbers.
Methods
.getPoint( t1 : number, t2 : number, target : Vector3 )
This method returns a vector in 3D space for the given interpolation factor. This vector lies on the NURBS surface.
| t1 |
The first interpolation factor representing the |
| t2 |
The second interpolation factor representing the |
| target |
The target vector the result is written to. |
