How to Embed and View 3D Models on Websites

Understanding the basics of 3D model integration

The ability to embed interactive 3D models on websites has transformed how game developers showcase their work, prototype ideas, and engage with their audience. Whether you’re looking to display character models, game environments, or interactive assets, integrating 3D content into your web presence can significantly enhance user experience and engagement.

Modern web technologies have made 3D integration increasingly accessible, even for developers without specialized 3D expertise. Let’s explore the methods, tools, and best practices for seamless web-based 3D integration that can help you showcase your game assets effectively.

Can you put a 3D model on a website?

Yes, absolutely! Modern web technologies make it entirely possible to embed interactive 3D models on websites. There are two primary approaches:

1. JavaScript frameworks for custom integration

For developers comfortable with coding, JavaScript libraries provide powerful tools for creating customized 3D experiences:

• Three.js: A popular JavaScript library that simplifies WebGL implementation, giving you extensive control over 3D rendering
• Babylon.js: A powerful engine for building games and 3D experiences with HTML5 and WebGL
• A-Frame: A web framework that simplifies Three.js with an HTML-based approach, particularly useful for AR/VR applications

These frameworks offer maximum flexibility but require JavaScript knowledge to implement effectively.

2. No-code/low-code embedding solutions

For those seeking simpler implementation without coding expertise:

• iFrame embedding: Platforms like Sketchfab provide embed codes you can paste directly into your site
• Turnkey platforms: Services like VNTANA and ARitize3D offer drag-and-drop solutions for 3D model integration
• AI-powered generation: Alpha3D’s AI 3D Model Generator allows you to create and embed 3D models from text prompts or 2D images

These solutions are ideal for quickly adding 3D content to your website without extensive development work.

Choosing the right 3D file format for web

The file format you choose significantly impacts loading times, visual quality, and compatibility. Here are the most common formats for web 3D:

Format	Best For	Pros	Cons
.glb/.gltf	Web delivery	Optimized for web, supports materials and animations	Limited editing capabilities
.fbx	Animation/game dev	Versatile, widely supported in Unity/Unreal	Larger file size
.obj	Basic geometry	Simple, widely compatible	Limited animation support

For web-based 3D viewers, .glb (binary GLTF) has become the standard due to its efficiency and web optimization. The compact nature of .glb files ensures faster loading times, which is crucial for maintaining user engagement on your website.

If you’re creating 3D models from photos, many platforms will automatically convert your output to web-friendly formats, saving you the hassle of manual conversion.

Step-by-step: Embedding a 3D model with Three.js

For developers who want complete control over their 3D integration, here’s a simplified workflow using Three.js:

1. Import the library into your HTML:

   <script src="https://cdn.jsdelivr.net/npm/three@0.132.2/build/three.min.js"></script>
   <script src="https://cdn.jsdelivr.net/npm/three@0.132.2/examples/js/loaders/GLTFLoader.js"></script>

2. Set up the scene and camera:

   const scene = new THREE.Scene();
   const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
   const renderer = new THREE.WebGLRenderer();
   renderer.setSize(window.innerWidth, window.innerHeight);
   document.body.appendChild(renderer.domElement);

3. Load your 3D model:

   const loader = new THREE.GLTFLoader();
   loader.load('path/to/your/model.glb', function(gltf) {
     scene.add(gltf.scene);
   });

4. Add lighting and controls:

   const light = new THREE.AmbientLight(0xffffff, 0.5);
   scene.add(light);
   
   const controls = new THREE.OrbitControls(camera, renderer.domElement);

5. Create the animation loop:

   function animate() {
     requestAnimationFrame(animate);
     controls.update();
     renderer.render(scene, camera);
   }
   animate();

This approach gives you complete control over how your 3D models are presented, allowing for custom interactions that match your game’s aesthetic and mechanics.

The no-code approach: Using embed platforms

If you prefer a simpler solution without coding, platforms like Sketchfab make it easy:

1. Upload your model to a platform like Sketchfab
2. Customize the viewer settings (background, lighting, initial camera position)
3. Copy the embed code provided by the platform
4. Paste the code into your website’s HTML where you want the 3D model to appear

This approach is particularly useful when you need to quickly showcase 3D models generated from video or other sources without extensive development work.

For example, if you’ve created character models for your game, Sketchfab allows players to view them from all angles, zoom in on details, and even see animations—all directly in their browser without downloading special software.

How to display .glb files in HTML

The simplest way to display .glb files in HTML is using the Model Viewer web component developed by Google:

1. Import the component:

   <script type="module" src="https://unpkg.com/@google/model-viewer/dist/model-viewer.min.js"></script>

2. Add the model viewer element:

   <model-viewer
     src="path/to/model.glb"
     alt="3D model"
     auto-rotate
     camera-controls
     shadow-intensity="1"
     style="width: 100%; height: 500px;">
   </model-viewer>

This approach requires minimal coding while still providing an interactive 3D viewing experience. Model Viewer also offers additional features like AR viewing on compatible mobile devices, allowing users to place your game characters or objects in their physical space—a powerful marketing tool for your game.

Optimizing 3D models for web performance

To ensure smooth loading and interaction with your 3D models:

1. Reduce polygon count: Aim for models under 100k polygons for optimal web performance
2. Compress textures: Use formats like .jpg or .webp with reasonable dimensions (1024×1024 or smaller)
3. Implement level of detail (LOD): Show simpler versions of models when zoomed out
4. Use draco compression: For .glb files, draco compression can reduce file size by up to 90%
5. Lazy loading: Only load models when they’re about to enter the viewport

These optimizations are particularly important for game developers who want to showcase detailed assets without causing performance issues. When using reference images for 3D modeling, keep the final web optimization in mind to avoid creating unnecessarily complex models.

As a rule of thumb, web-based 3D models should be lighter than their in-game counterparts, focusing on visual impact rather than intricate detail that may not be noticeable in a web viewer.

Enhancing user experience with interactive features

Beyond basic model viewing, consider these interactive features to make your 3D content more engaging:

• Annotations: Add hotspots that reveal information about character abilities or weapon stats when clicked
• Animations: Trigger character animations based on user interaction to showcase gameplay mechanics
• AR viewing: Enable “View in your space” functionality for mobile users to see game characters in their environment
• Cross-sections: Allow users to see inside complex models like vehicles or buildings
• Material swapping: Let users change character skins, armor variations, or weapon appearances

For example, if you’ve developed a character customization system for your game, you could create a web-based preview that lets potential players experiment with different combinations—generating excitement while showcasing your game’s depth.

Testing across devices and browsers

Before launching, test your 3D implementation across:

• Different browsers: Chrome, Firefox, Safari, Edge
• Mobile devices: iOS and Android phones/tablets
• Connection speeds: Test on throttled connections to simulate slower internet
• Various screen sizes: From phones to large desktop monitors

You can use online services like Alpha3D’s online 3D model viewer to quickly check how your models will appear across different devices without complex setup.

Remember that mobile users might have limited bandwidth or processing power, so offering a simplified version for these devices can improve accessibility while still conveying the essence of your 3D assets.

Practical applications for game developers

Game developers can leverage web-based 3D models in numerous ways:

• Interactive portfolios: Showcase character models and environments from your game to attract players or potential employers
• Pre-release marketing: Let players explore assets before game launch to build anticipation
• Community engagement: Allow modders to preview their creations and share them with other players
• Design feedback: Gather input on character designs or environments early in development
• Documentation: Create interactive tutorials showing game mechanics or interface elements

By using tools like Alpha3D’s 3D design studio, game developers can rapidly create and iterate on 3D assets that can be shared both in-game and on the web.

One indie studio used this approach effectively by embedding customizable character models on their crowdfunding page, allowing backers to interact with the game’s art style before the game was even built—resulting in a funding campaign that exceeded its goal by 200%.

The future of 3D on the web

Web-based 3D is evolving rapidly with emerging technologies:

• WebGPU: The successor to WebGL promises significantly better performance, allowing for more complex game assets to be displayed
• AI-generated models: Tools like Alpha3D that can make 3D models from photos are democratizing 3D content creation
