ParametricGeometry

This class can be used to generate a geometry based on a parametric surface.

Reference: Mesh Generation with Python

Code Example

const geometry = new THREE.ParametricGeometry( klein, 25, 25 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const klein = new THREE.Mesh( geometry, material );
scene.add( klein );

Import

ParametricGeometry is an addon, and must be imported explicitly, see Installation#Addons.

import { ParametricGeometry } from 'three/addons/geometries/ParametricGeometry.js';

Constructor

new ParametricGeometry( func : ParametricGeometry~Func, slices : number, stacks : number )

Constructs a new parametric geometry.

func

The parametric function. Default is a function that generates a curved plane surface.
slices

The number of slices to use for the parametric function.

Default is 8.
stacks

The stacks of slices to use for the parametric function.

Default is 8.

Properties

.parameters : Object

Holds the constructor parameters that have been used to generate the geometry. Any modification after instantiation does not change the geometry.

Type Definitions

.Func( u : number, v : number, target : Vector3 )

Parametric function definition of ParametricGeometry.

u

The u coordinate on the surface in the range [0,1].
v

The v coordinate on the surface in the range [0,1].
target

The target vector that is used to store the method's result.
