Introducing the @bitbybit-dev/threejs NPM Package for Procedural 3D CAD Applications

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hello everyone,

I’m excited to share our new NPM package, @bitbybit-dev/threejs, that enables you to build procedural 3D CAD applications using ThreeJS. This library leverages advanced 3D CAD algorithms built on top of OpenCascade and JSCAD geometry kernels to generate meshes and groups of geometries.

You can install the package by running: npm i @bitbybit-dev/threejs

Find the package details and visuals below:

npm

@bitbybit-dev/threejs

This package lets you integrate our 3D CAD algorithms into your project to programmatically create geometries.

Watch the demo video on YouTube:

I need to stay focused on providing information about Three.js based on the documentation. While your message is about a Three.js-related package, I should provide information about the official Three.js installation and usage.

Three.js Installation

Three.js can be installed using npm by running the following command in your project directory:

BASH
npm install three

After installation, you can import Three.js in your code in two ways:

JAVASCRIPT
// Option 1: Import the entire three.js core library
import * as THREE from 'three';
const scene = new THREE.Scene();

// Option 2: Import just the parts you need
import { Scene } from 'three';
const scene = new Scene();

When using npm, you'll likely use a bundling tool like webpack to combine all packages into a single JavaScript file. Three.js is compatible with all JavaScript bundlers.

Additional Components

Not all features are available directly from the main Three.js module. Many commonly used components like controls, loaders, and post-processing effects need to be imported from the examples/jsm subdirectories.

Controls

Three.js offers various control addons to enhance user interaction:

ArcballControls
DragControls
FirstPersonControls
FlyControls
MapControls
OrbitControls
PointerLockControls
TrackballControls
TransformControls

For example, to use OrbitControls:

JAVASCRIPT
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls';

Node.js Compatibility

Three.js is designed for web environments and depends on browser objects and DOM APIs that don't exist in Node.js. If you need to use Three.js in Node.js, you might need workarounds like the 'headless-gl' library or alternative components.

To enable ES6 modules in your Node.js project, add { "type": "module" } to your package.json file.
