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 code is based on an article by Andreas Kahler, with a few optimizations.
Example
import icomesh from 'icomesh';
// generate an icosphere with 4 subdivisions
const {vertices, triangles} = icomesh(4);
API
icomesh(order = 4)
Generates an icosphere mesh with order
subdivisions (4
by default, 10
max).
Returns an object with:
vertices
: AFloat32Array
array ofx, y, z
vertices.triangles
: AUint16Array
orUint32Array
array of triangle indices.
You can reuse vertex data for normals because they are equal for a unit sphere.
