Chapter 40: ParametricGeometry

Core Idea

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

Reference: Mesh Generation with Python

Key Concepts

• parameters : Object: Holds the constructor parameters that have been used to generate the geometry. Any modification after instantiation does not change the geo…

Code Examples

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 );

• What it demonstrates: Typical usage of ParametricGeometry.

Constructor

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

Properties

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

Key Takeaways

1. ParametricGeometry extends: EventDispatcher → BufferGeometry
2. Most relevant properties: parameters.
