icomesh

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.


Example

``js
import icomesh from 'icomesh';

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

API

$3

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

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

- ES module build on unpkg
