Package Exports

icomesh

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (icomesh) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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

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:

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:
