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.

Browser 3D aquarium game: pilot a yellow submarine pod among goldfish and corals

A one-shot browser game from GPT-6 Astra: a tiny submarine glides through a teal glass tank full of fish, coral and kelp, with a score HUD.

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

Build brief by Wandy3D

The author didn't share a prompt, so we wrote down how to recreate this build.

Build a one-file browser 3D game set inside a glass aquarium tank. The player pilots a small round yellow submarine pod along a sandy floor dotted with smooth grey rocks, pink and purple corals, orange sea fans and swaying green kelp. Shoals of stylised goldfish and small coloured fish swim around and react to the pod. Use a calm teal-blue palette with light shafts from above, a rippling water surface seen from below and soft depth fog. Add a minimal HUD with a score counter, a distance readout, health or energy bars and a level title card reading Sunlit Shoals that fades in and out. Controls: keyboard to steer and move the pod, with a smooth chase camera. Give the pod a small interaction with the fish, such as scooping or scaring them, that raises the score. Model every object from simple procedural geometry so the game runs smoothly in the browser. Done means the scene loads instantly and can be played for several minutes.

How to use this prompt

Paste the build brief into GPT-6 Astra and ask for a single HTML file that runs in the browser.
Change the creature, the habitat, the palette or the level name, and describe the controls you prefer.
Open the file, play, then ask for new goals, more fish species or extra levels to iterate.
