๐ŸŒŸ Three Glow Mesh

Create glow mesh with any ThreeJS geometry.

three-glow-mesh is based off the awesome work by stemkoski. The original idea and motivation is laid out by the author in this link.

Install

npm install three-glow-mesh

Note that three-glow-mesh requires three >= 0.102.0 as a peer dependency.

Use

Import createGlowMesh and supply any ThreeJS geometry and a valid options object.

Here is an example of a common way to create a glow mesh:

import { Mesh, Renderer, Scene } from 'three';
import { createGlowMesh, defaultOptions } from './three-glow-mesh';

const originalMesh = new Mesh(...);

// We can optionally import and overwrite the defaultOptions
const options = {
  ...defaultOptions,
  backside: true,
  coefficient: 0.5,
  color: 'gold',
  size: 2,
  power: 1
};
// You can reference the original mesh geometry or provide a custom one.
const glowMesh = createGlowMesh(originalMesh.geometry, options);
// You can add the glow mesh to any ThreeJS object (e.g. camera, scene),
// but it is common practice to just add and associate it with the original mesh.
originalMesh.add(glowMesh);

// three boilerplate (this is pseudocode)
const scene = new Scene();
const renderer = new WebGLRenderer({antialias: true});
scene.add(mesh);
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
renderer.render(scene, camera);

Examples

In the following Codesandbox instances, edit the options variables to experiment with glow effects! You can test various values of coefficient, color, power using this tool.
