How to build interactive 3D websites with AI

The Rundown: Transform any image idea into a fully functional 3D website using ChatGPT for image generation, Hunyuan 3D for model conversion, and AI coding tools for instant web development.

🧰 Who is this useful for:

  • Web developers wanting to add 3D elements without complex modeling skills
  • Entrepreneurs building interactive product showcase websites
  • Creative professionals exploring new web experiences
  • Students learning modern web development with AI assistance


STEP 1: Generate Your 3D Image with ChatGPT

Head over to ChatGPT and use a specific prompt structure for optimal results. The key is requesting a white background for easier 3D conversion.

Example prompt: "Create a 3D image model of a Ninja Turtle with a white background"

You can replace "Ninja Turtle" with any object you want for your website - a product, character, or decorative element. The white background is crucial as it helps the AI model better isolate your object during the 3D conversion process.

Once ChatGPT generates your image, download it to your computer. This will serve as the foundation for your 3D model.

STEP 2: Convert to 3D Model Using Hunyuan 3D

Navigate to Hugging Face and search for "Hunyuan 3D 2.1" or visit the space directly. This powerful, completely free tool converts 2D images into 3D models.

Upload your ChatGPT-generated image to the interface. You'll see two important options:

  • First, click "Generate Texture Shape" to create the initial 3D structure
  • Then, click "Transform" to finalize the model for download

The process will generate a GLB file. This is your 3D model that you'll use in your website. Download this file and save it in a dedicated project folder on your computer.

STEP 3: Create Your Interactive Website with AI Coding

Choose your preferred AI coding tool: Windsurf, Replit, Cursor, or any similar platform. Create a new project and upload your GLB file to the project folder. For this tutorial, we'll use Windsurf as it provides excellent real-time preview capabilities, but the workflow is compatible with all major AI coding platforms.

In your AI coding tool, use a prompt like this:

"I have the following 3D GLB file. Create a Toy Shop website that rotates the 3D model on the X axis when the user scrolls down."

You can customize this prompt based on your vision:

  • Change "Toy Shop" to match your theme (Portfolio, Product Showcase, Gallery, etc.)
  • Modify the animation (rotate on Y axis, scale up/down, move side to side)
  • Add specific styling requests (modern, minimalist, colorful, etc.)

The AI will generate HTML, CSS, and JavaScript files using Three.js library to create your interactive 3D website. Most tools will provide a live preview so you can see your creation immediately.


STEP 4: Refine and Enhance

After the initial generation, you can improve your website with follow-up prompts:

  • "Enhance the UI and make it more modern"
  • "Add a navigation menu and footer"
  • "Make the 3D model stay visible while scrolling"
  • "Change the background color and add lighting effects"

The great thing about this workflow is that you can iterate quickly, testing different animations and layouts until you achieve the perfect result.

Pro tip: Experiment with different scroll-based animations like "scale the model as user scrolls" or "move the model horizontally during scroll" to create unique interactive experiences that engage your visitors.
