An interactive Three.js-powered 3D product configurator for WooCommerce — let customers customize materials, textures, and geometry in real time.

== Description ==

[DEMO](https://web-support.eu/customizer/showcase/?utm_source=wporg&utm_medium=plugin_listing&utm_campaign=demo)

Let customers build their perfect product in 3D — swap materials, hide parts, and share their design. Powered by Three.js, built for WooCommerce.
 
**Key features:**

* Real-time 3D model viewer powered by Three.js (WebGL)
* PBR (Physically Based Rendering) material support — base color, roughness, normal, AO, metalness, and displacement maps
* Per-step customization: define multiple configuration steps (e.g. Upper, Sole, Logo), each targeting specific model meshes
* Bulk material assignment in the admin
* Geometry visibility toggles — show or hide mesh groups per option
* Undo / redo history
* URL-based configuration sharing — customers can share their exact design via a link
* Download a PDF preview
* AR view on supported mobile devices
* HDR environment map for realistic lighting
* Background color switcher
* Customization data saved to the WooCommerce order as line-item meta
* Reusable texture library via a dedicated Custom Post Type


**Free vs Premium:**

The free version is fully functional for single-material customization. Premium unlocks advanced PBR workflows and productivity features for studios managing large product catalogs.

== Source Code & Build Instructions ==

**All source code is human-readable and included in this plugin.**

The `/js/` folder contains the original, uncompiled JavaScript source files:
* `customizer.js` — Main 3D configurator frontend logic
* `model-scanner.js` — 3D model mesh detection and analysis
* `material-preview.js` — Material preview rendering
* `ui.js` — UI state management and interactions
* Admin scripts in `/admin/js/` — Dashboard-specific functionality

The `/dist/` folder contains pre-compiled, production-ready bundles. These are generated by bundling the source files with their dependencies (three.js, pdf-lib, lucide) using Webpack. **The `/dist/` folder is auto-generated output and not part of the source code.**

**Rebuilding from Source:**

This plugin uses Webpack to compile and minify JavaScript, bundling dependencies to keep the plugin size manageable (avoiding the need to distribute `node_modules`).

Requirements:
* Node.js (v14 or newer)
* npm (included with Node.js)

Build commands:
```
npm install              # Install dependencies from package.json
npm run dev             # Development build with watch mode (rebuilds on file changes)
npm run build           # Production build (minified and optimized)
```

**Dependencies:**
* **three.js** — WebGL 3D rendering library (licensed under MIT)
* **pdf-lib** — PDF generation for preview downloads (licensed under Apache 2.0)
* **lucide** — Icon library (licensed under MIT)
* **webpack** — Module bundler (licensed under MIT)

All original code is GPLv2 or later. Third-party dependencies follow their respective open-source licenses, listed in `package.json`.

== Installation ==

1. Upload the `product-customizer` folder to `/wp-content/plugins/`.
2. Activate the plugin through the **Plugins** menu in WordPress.
3. Ensure WooCommerce is installed and active.
4. Navigate to **Model Textures** in the WordPress admin and create texture entries. Each texture can include a base-color image (featured image) plus optional PBR maps and scalar material properties.
5. Open any WooCommerce product and locate the **3D Configurator** metabox.
6. Upload or select a `.glb` / `.gltf` model using the **Select Model** button.
7. Click **Scan Model** to auto-detect mesh names from the file.
8. Add one or more **Steps** and assign **Options** (textures or geometry toggles) to each step.
9. Save the product. The 3D configurator will now appear on the product's front-end page.
10. Visit **Model Textures → Global Settings** to configure camera position, zoom limits, background colors, and an optional HDR environment map.


== Frequently Asked Questions ==

= What 3D file formats are supported? =
GLB (binary GLTF) is the recommended format. GLTF (JSON-based) is also supported. The plugin registers these MIME types with WordPress so they can be uploaded through the standard Media Library.

= Can I use multiple HDR environment maps per product? =
The HDR environment map is a global setting. All products share the same HDR file. Per-product HDR support is planned for a future release.

= Why does the 3D viewer not appear on a product page? =
The configurator only renders when the product has a valid `.glb` model URL AND at least one configured step with at least one option. Check the **3D Configurator** metabox on the product.

= How is the customization saved to the order? =
When a customer clicks **Add to cart**, the current configuration is sent as a JSON payload. Each selected option (part → material name) is stored as a WooCommerce line-item meta entry and is visible on the order detail and in emails.

= Is this compatible with WooCommerce variable products? =
The plugin targets simple products. Variable product support is not officially tested.

= Are the bundled JavaScript files minified? =
Yes. The source files are included in the `js/` directory and the `webpack.config.js` build configuration is included in the plugin package.
