TeapotGeometry

Tessellates the famous Utah teapot database by Martin Newell into triangles.

The teapot should normally be rendered as a double sided object, since for some patches both sides can be seen, e.g., the gap around the lid and inside the spout.

Segments 'n' determines the number of triangles output. Total triangles = 32 2 n n - 8 n (degenerates at the top and bottom cusps are deleted).

Code based on SPD software Created for the Udacity course Interactive Rendering

Code Example

const geometry = new TeapotGeometry( 50, 18 );
const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
const teapot = new THREE.Mesh( geometry, material );
scene.add( teapot );

Import

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

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

Constructor

new TeapotGeometry( size : number, segments : number, bottom : boolean, lid : boolean, body : boolean, fitLid : boolean, blinn : boolean )

Constructs a new teapot geometry.

size | Relative scale of the teapot. Default is 50.
---|---
segments | Number of line segments to subdivide each patch edge. Default is 10.
bottom | Whether the bottom of the teapot is generated or not. Default is true.
lid | Whether the lid is generated or not. Default is true.
body | Whether the body is generated or not. Default is true.
fitLid | Whether the lid is slightly stretched to prevent gaps between the body and lid or not. Default is true.
blinn | Whether the teapot is scaled vertically for better aesthetics or not. Default is true.
