ThreePipe is a 3D framework built on top of [three.js](https://threejs.org/) in TypeScript with a focus on rendering quality, modularity, and extensibility.

Key features include:
- Simple, intuitive API for creating 3D model viewers/configurators/editors on web pages, with many built-in presets for common workflows and use-cases.
- Companion [editor](https://threepipe.org/examples/tweakpane-editor/) to create, edit and configure 3D scenes in the browser.
- Modular architecture that allows you to easily extend the viewer, scene objects, materials, shaders, rendering, post-processing and serialization with custom functionality.
- Plugin system along with a rich library of built-in plugins that allows you to easily add new features to the viewer.
- [uiconfig](https://github.com/repalash/uiconfig.js) compatibility to automatically generate configuration UIs in the browser.
- Modular rendering pipeline with built-in deferred rendering, post-processing, RGBM HDR rendering, etc.
- Material extension framework to modify/inject/build custom shader code into existing materials at runtime from plugins.
- Extendable asset import, export and management pipeline with built-in support for gltf, glb, obj+mtl, fbx, materials(pmat/bmat), json, zip, png, jpeg, svg, webp, ktx2, ply, 3dm and many more.
- Automatic serialization of all viewer and plugin settings in GLB(with custom extensions) and JSON formats.
- Automatic disposal of all three.js resources with built-in reference management.

## Getting Started

### HTML/JS Quickstart (CDN)

```html

<canvas id="three-canvas" style="width: 800px; height: 600px;"></canvas>
<script type="module">
  import {ThreeViewer, DepthBufferPlugin} from 'https://threepipe.org/dist/index.mjs'

  const viewer = new ThreeViewer({canvas: document.getElementById('three-canvas')})

  // Add some plugins 
  viewer.addPluginSync(new DepthBufferPlugin())
  
  // Load an environment map
  const envPromise = viewer.setEnvironmentMap('https://threejs.org/examples/textures/equirectangular/venice_sunset_1k.hdr')
  const modelPromise = viewer.load('https://threejs.org/examples/models/gltf/DamagedHelmet/glTF/DamagedHelmet.gltf', {
    autoCenter: true,
    autoScale: true,
  })

  Promise.all([envPromise, modelPromise]).then(([env, model]) => {
    console.log('Loaded', model, env, viewer)
  })
</script>
```

### React

A sample [react](https://react.dev) component in tsx to render a model with an environment map.

```tsx
import React from 'react'
function ThreeViewerComponent({src, env}: {src: string, env: string}) {
  const canvasRef = React.useRef(null)
  React.useEffect(() => {
    const viewer = new ThreeViewer({canvas: canvasRef.current})

    const envPromise = viewer.setEnvironmentMap(env)
    const modelPromise = viewer.load(src)
    Promise.all([envPromise, modelPromise]).then(([env, model]) => {
      console.log('Loaded', model, env, viewer)
    })
    
    return () => {
      viewer.dispose()
    }
  }, [])
  return (
     <canvas id="three-canvas" style={{width: 800, height: 600}} ref={canvasRef} />
  )
}
```

Another example with Vue SFC(Single file component): https://threepipe.org/examples/#vue-sfc-sample/

### Svelte

A sample [svelte](https://svelte.dev/) component in js to render a model with an environment map.

```html
<script>
    import {onDestroy, onMount} from 'svelte';
    import {ThreeViewer} from 'threepipe'; 

    let canvasRef;
    let viewer;
    onMount(() => {
        viewer = new ThreeViewer({canvas: canvasRef});

        const envPromise = viewer.setEnvironmentMap('https://threejs.org/examples/textures/equirectangular/venice_sunset_1k.hdr');
        const modelPromise = viewer.load('https://threejs.org/examples/models/gltf/DamagedHelmet/glTF/DamagedHelmet.gltf');

        Promise.all([envPromise, modelPromise]).then(([env, model]) => {
          console.log('Loaded', model, env, viewer)
        })
    });
    onDestroy(() => viewer.dispose())
</script>

<canvas bind:this={canvasRef} id="three-canvas" style="width: 800px; height: 600px"></canvas>
```

Check it in action: https://threepipe.org/examples/#svelte-sample/

### NPM/YARN

### Installation

```bash
npm install threepipe
```

### Loading a 3D Model

First, create a canvas element in your HTML page:
```html
<canvas id="three-canvas" style="width: 800px; height: 600px;"></canvas>
```

Then, import the viewer and create a new instance:

```typescript
import {ThreeViewer, IObject3D} from 'threepipe'

// Create a viewer
const viewer = new ThreeViewer({canvas: document.getElementById('three-canvas') as HTMLCanvasElement})

// Load an environment map
await viewer.setEnvironmentMap('https://threejs.org/examples/textures/equirectangular/venice_sunset_1k.hdr')

// Load a model
const result = await viewer.load<IObject3D>('https://threejs.org/examples/models/gltf/DamagedHelmet/glTF/DamagedHelmet.gltf', {
    autoCenter: true,
    autoScale: true,
})
```

That's it! You should now see a 3D model on your page.

The 3D model can be opened in the [editor](https://threepipe.org/examples/tweakpane-editor/) to view and edit the scene settings, objects, materials, lights, cameras, post-processing, etc. and exported as a GLB file. All settings are automatically serialized and saved in the GLB file, which can be loaded into the viewer. Any plugins used in the editor can be added to the viewer to add the same functionality. The plugin data is automatically loaded(if the plugin is added) when the model is added to the scene.

The viewer initializes with a Scene, Camera, Camera controls(Orbit Controls), several importers, exporters and a default rendering pipeline. Additional functionality can be added with plugins.

Check out the GLTF Load example to see it in action or to check the JS equivalent code: https://threepipe.org/examples/#gltf-load/

Check out the [Plugins](https://threepipe.org/guide/features.html#plugin-system) section to learn how to add additional functionality to the viewer.
