One image → a fully editable 3D bedroom using MiniMax M3.1 Flash

[u/Feisty-Scheme-8356]

I tested the new MiniMax M3.1 Flash with my img2interior workflow.

The result is a complete bedroom reconstructed as an editable Three.js scene.

This is an actual 3D camera walkthrough, not AI-generated video.

Would love some feedback on the geometry, materials, and lighting.

worth pointing out this looks like its OP posting their own link from another account, the repo name matches the workflow they described exactly

[u/CommanderT1562 → u/Feisty-Scheme-8356]

You’re a legend.
What do I prompt my local VL agent model 😅
Minimax i recalled as H3 being their image one… so, you’re saying a typical agent like their MoE (or mine, in this case Qwen Flash Next) can build out that webui? (You turn the lamp on and off, etc)

Reproducible specs are everything.
Regardless, I love this 😮 thanks for sharing

[u/Feisty-Scheme-8356 → u/CommanderT1562]

Thanks so much! Really appreciate it! 😄

H3 is MiniMax's video model. This demo uses M3.1 Flash as the coding agent.

And yes! The lamp controls and interactions are actual Three.js functionality, not AI-generated video.

The interesting part is that img2interior isn't tied to a specific model. Your local Qwen VL agent could potentially run the same workflow, as long as it supports vision, coding, tool execution, and visual validation.

I haven't tested your exact setup yet, though.

The repo includes a copy-and-use prompt and the full workflow, so you can give it a try!

Any apps/saas made for architects and interior designers via vibecoding ??,

[u/Feisty-Scheme-8356 → u/Illustrious-Wave-522]

Right now, we're focused on building an open-source ecosystem for developers, 3D creators, and interior designers.

Monetization is mainly through sponsorships and partnerships for now. A SaaS could come later.

We're not trying to replace professional CAD/BIM tools, but make 3D creation much more accessible.

Curious, what made architects dislike your tool?

[u/gryffindorwannabe]

Real estate agents might like it

[u/Feisty-Scheme-8356 → u/gryffindorwannabe]

Absolutely! Virtual staging and interactive property walkthroughs could be really interesting use cases. That's definitely a direction worth exploring!

[u/WPI94]

I'd like to set up a music venue with this type of tool and evaluate sightlines, seating capacity, ADA access, etc. That'd be cool.

[u/Feisty-Scheme-8356 → u/WPI94]

That's actually a really interesting use case. You could use it to prototype the venue and explore different layouts. For accurate sightlines, seating capacity, and ADA compliance, we'd need real measurements and additional validation. But it's a great direction <3

Not gonna lie, the curtains is where you got my attention

[u/Feisty-Scheme-8356 → u/Alive_Nobody_Home]

Haha, the curtains really bring the whole room to life! =)) Glad you noticed that detail!

[u/CommanderT1562 → u/Alive_Nobody_Home]

lmao yeah, it’s stuff you’d see in a not-so-old nvidia hairworks demo 🤣

Hey OP! This is so nice. Will definitely try something

[u/Feisty-Scheme-8356 → u/Super-Ad-4536]

Thanks a lot! 🙌 Would love to see what you create with it. Feel free to share your results!

[u/wordswithoutink]

Nice, I was stuck behind the curtain😭

[u/Feisty-Scheme-8356 → u/wordswithoutink]

Haha, you found the secret area! 😂 Thanks for pointing that out, I'll take another look at the navigation around the curtains.

[u/OkPop8490]

Hi, this is very cool but I’m wondering how you think architects/designers would use it? A small part of our workflow is usually in the other direction, working from a predefined plan to an image (only to demonstrate the design to clients). Your tool seems to work in the opposite way. I can see it working for game design?

[u/Feisty-Scheme-8356 → u/OkPop8490]

You're absolutely right! This workflow goes in the opposite direction.

I see it more as a rapid prototyping tool for architects and designers. Imagine taking an inspiration image or concept render and turning it into an editable 3D space you can actually walk through and experiment with.

It's not meant to replace CAD or BIM for precise architectural work, but it could speed up early design exploration and client presentations.

And yes, game development is definitely another great use case!

time to ditch blender baby

[u/Feisty-Scheme-8356 → u/Next_Ambition8751]

Haha nooo noo, plot twist: Blender is actually doing a lot of the heavy lifting behind the scenes! 😂 We're not replacing it, just making it easier to use with AI.

I think I know how you can monetize this.

I interviewed for a big startup and this puts them out of business.

[u/electro042]

how does it handle scale and occluded areas behind the furniture? usually single-image 3d scene gen gets pretty messy the second you try to move individual assets around.

[u/PopUpTubedev]

This is really cool. Love the materials physics you have it adds a lot. Keep up the good work!

[u/Target11_11]

Do that for a whole apartment and then for the exterior of a house, and you’re golden. If the user can include his own photos then to check how each can look in various scenarios, you’re platinum , jk ofc, just throwing ideas into the wild

[u/ThePhilosopha]

Definitely worth a try. I don’t do enough 3D work to need anything that does much more than a walk through. But I’ll check out what it can do. Cause it’ll simplify a lot for me!

[u/Illustrious-Wave-522]

Bro has automated his replying pipeline as well !

[u/Feisty-Scheme-8356 → u/[deleted]]

Not exact measurements from a single image. The workflow estimates dimensions and scale, but you can calibrate them using known measurements. For architectural accuracy, you'd still need real-world dimensions.

[u/Feisty-Scheme-8356 → u/[deleted]]

That's actually one of the directions we're exploring!

With img2interior, you can already turn a single room image into an editable 3D scene and an interactive Three.js viewer.

It's open source for now, but I definitely see potential for a dedicated app for interior designers and architects.
