How does AI 3D model generation work?

Upload a photo — or several views, or describe the object in words — and the AI builds a textured 3D model, usually in a few minutes. View it in the browser and export it as GLB, FBX, OBJ, USDZ or STL for Unity, Unreal Engine, Blender and other tools.

What objects can I convert to 3D?

Almost anything you can photograph or describe: furniture, props, characters, creatures, gadgets, food, buildings and more.

Is Wandy3D free to use?

Yes. New accounts get free credits and free accounts get a credit top-up every month, so you can generate and view models in the browser at no cost, on every model version including Wandy 1.2. PRO plans add credits every month and unlock downloads in every format.

What 3D file formats does Wandy3D support?

GLB, GLB with Draco compression, FBX, OBJ (with MTL and textures), USDZ and STL. For 3D printing there are watertight STL and 3MF files, and for games a quad remesh with baked PBR textures as GLB or FBX.

How is Wandy3D different from other AI 3D generators?

Wandy3D covers the whole path from input to a usable file in one browser workspace: photo, multi-view or text input, edit by prompt, retexturing, quad remesh, print-ready export and a community to share models.

Interactive 3D jet engine with cutaway, x-ray and exploded view

A model comparison: Gemini 4 Pro and GPT-6 Astra got the same prompt for a Three.js jet engine viewer, and Gemini 4 Pro's build was the more detailed one.

Code alone gets you simple shapes. Wandy 2 turns one photo into a textured 3D model you can use in the same scene.

Gemini 4 Pro prompt

Use three.js to build a 3D interactive display of an aircraft engine on a webpage. 
Please refer to Jigspace's interaction design philosophy to achieve a realistic model with near 1:1 high-fidelity restoration, fully preserving material and texture details such as metal, pipelines, and blades. Interactive features must include: step-by-step disassembly animation, exploded view of components, and part descriptions and principle explanations triggered by click or hover. 
Overall, it must support smooth camera control and friendly human-computer interaction, ensuring a smooth experience on the web that fully showcases the engine's structure and working principles.

How to use this prompt

Paste the prompt into Gemini 4 Pro (or GPT-6 Astra to compare) in your coding tool and ask for a Three.js web page.
Swap the aircraft engine for another machine, and edit the list of interactions such as x-ray, airflow or part labels.
Run the page, orbit and disassemble the engine, then ask for sharper materials or clearer part descriptions.
