How to build a 3D website with Gemini and Orbital 3D

The approach

Build the 3D scene in Orbital, then use Gemini to help create the HTML interface around it. Give each layer a clear job: the scene communicates shape and movement, while the page carries the heading, explanation, navigation and call to action. A successful result feels like one composition even though the two layers are built separately.

Start with three moments in the story

Write down what a visitor should understand at the beginning, middle and end. For a product launch, that could be the overall silhouette, one construction detail, and the finished product beside a purchase link. This gives the camera a reason to move and gives the HTML sections a clear order.

Sketch the layout at phone width before refining the desktop scene. If the product needs half a wide screen and the text needs the other half, decide how they will stack on a phone. A shorter sequence with a stable opening frame is often easier to adapt than a long camera flight.

Compose the scene in Orbital

Open the studio, add your model and frame it with the camera. Adjust scale and orientation before creating motion; changing the model’s center later can change how a camera transition feels. Refine lighting from the viewing angles you actually plan to use, especially if the object has reflective or transparent surfaces.

Set up the key views and preview their transitions. Leave deliberate space for the page copy. Treat the published scene or export as a real deliverable to test, rather than assuming every editor interaction will behave identically in every export format.

Give Gemini the layout and the actual embed

Supply the real viewer URL or exported integration code, your copy and the intended layout. Ask for headings, links and buttons in HTML, a responsive scene container, and a static fallback. Keep the scene’s existing identifiers and URLs intact. Review generated code before adding it to a live website.

A useful brief is: ‘Build a responsive landing page around this Orbital embed. Use three text sections: introduction, product detail and next step. Keep the text outside the canvas, reserve the right side for the scene on desktop, stack content on mobile, and keep the call to action reachable without completing the animation.’

Check the boundary between the page and the scene

A page that scrolls and a scene that has an animation are not automatically synchronized. An iframe has its own document and input handling. Use the integration supported by your chosen export and verify that page progress actually drives the intended camera movement. Do not ask an AI tool to invent a runtime API to connect them.

Test scrolling while the pointer is over the scene, reversing direction halfway through, and jumping directly to a lower section. Keep a simpler composition available when synchronization is unreliable. The page should still explain the product when the scene has not loaded.

Answer the questions behind the Reddit demo

The Orbital discussion on r/threejs prompted requests for a setup tutorial and questions about iframe integration and phone performance. Those are useful acceptance criteria for your own version: make the build understandable, choose a delivery format deliberately, and check the published experience on a real phone.

Keep the initial model focused, reduce unnecessary scene effects and check whether important detail survives at smaller texture sizes. If the page feels slow, separate download time from rendering cost. A smaller file can load faster while an expensive lighting or transparency setup still makes interaction feel sluggish.

Put it into practice

1. 01

   Write the three text sections and sketch desktop and phone layouts.

2. 02

   Build the scene, lighting and camera views in Orbital.

3. 03

   Give Gemini the actual export plus a specific HTML layout brief.

4. 04

   Test the integration, page scrolling and static fallback on the destination site.

Explore the AI 3D website builder for prompt examples, scene editing and publishing options. Start with a focused scene, then use the real embed or export when briefing your coding assistant.

Before you publish

• The headline and links work before the 3D scene appears.
• Scrolling over the scene does not trap the visitor.
• The phone layout keeps the product and copy readable.
• The final action is reachable with motion reduced or disabled.
