threejs-viewer

A repo to quickly display any model (fbx & gltf format with compression) using Three.js.

• GLTF supports gltf-pack, gltf-pipeline and Blender exports.
• gltf-pack compression uses vertex quantisation, gltf-pipeline uses DRACO compression

Installation

1. Clone the repo.
2. Run npm install to install all the dependencies
3. Use npm run dev to compile the project in development mode
4. Use npm run build to compile the project in production mode
5. Open index.html using Live Server

Notes

• index.html - Display the FBX model (by default) on the full page.
  • Source files:
    • app.js - (default script) Displays FBX Model
    • app2.js - Displays GLTF Model
    • app.scss
  • Output files: Generated by Webpack after you compile the project
    • bundle.js
    • main.css
  • Everything is written inside an exportable class named Sketch so it can be easily imported using ES6+ syntax.
  • To view GLTF model, change entry in webpack.config.js to app2.js and then compile the project using npm run dev.
  • In case your model is compressed with Blender or gltf-pipeline, DRACO compression is applied over the model so make sure you include the draco-files folder in your project.
  • In case your model is compressed with gltf-pack, it uses mesh quantisation to compress the model so make sure you correctly import the MeshoptDecoder from three module.
  • All animations are played by default if provided in the GLTF.
  • The model is displayed in MeshNormalMaterial, so in case normals are not provided, the model will be solid black.
