Icosphere is a type of geodesic polyhedron that provides a good quality triangular mesh approximation of a sphere with relatively evenly distributed vertices. This project is inspired by an article by Andreas Kahler.

Example

import icomesh from 'icomesh';

// generate an icosphere with 4 subdivisions
const {vertices, triangles} = icomesh(4);

API

icomesh(order = 4, uvMap = false)

Generates an icosphere mesh with order subdivisions (4 by default, 10 max). Returns an object with:

You can reuse vertex data for normals because they are equal for a unit sphere.

Install

Install with npm install icomesh or yarn add icomesh (module environments only), or use a browser build from CDN:
