Fast JavaScript icosphere mesh generation library for WebGL visualizations. Interactive demo:

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.

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

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

• vertices: A Float32Array array of x, y, z vertices.
• triangles: A Uint16Array or Uint32Array array of triangle indices.
• uv: if uvMap is true, a Float32Array of u, v values for mapping vertices to a texture with an equirectangular projection.

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

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

• ES module build on unpkg
• UMD build on bundle.run
