Interior AI demonstrates floor-plan input for its 3D room editor

• A floor plan can become a furnished 3D interior, though the latest demo misses windows and bathroom details.
• Walkthrough reconstruction took about five minutes on a VPS in a separate test. That timing applies to video input.
• Custom wallpaper and object materials can be applied before rendering the edited room as a photo.

Interior AI creator Pieter Levels has already removed Blender from the stack. He also wants to feed a 3D walkthrough into a video model such as Seedance to produce a photorealistic redesign video.

Interior AI’s newest demonstration starts with only a floor-plan image and produces a furnished 3D interior. Levels says the system has to imagine furniture from the limited information available.

He flags three failures:

• Apparent sliding windows facing the garden are missing.
• The bathtub is represented by a box.
• A toilet seat is not visible.

Generating a scene from a walkthrough video took about five minutes on a VPS, according to his follow-up. Levels says the video workflow does not require LiDAR.

The initial live prototype used headless Blender running on his server. He announced it roughly three hours after proposing the feature.

The public product page now advertises video upload, furniture movement, wall painting and photorealistic renders from selected viewpoints. Interior AI’s FAQ says new customers receive an emailed login link immediately after payment.

For four years, Interior AI largely followed a photo-in, redesign-out workflow. The new editor exposes controls over the reconstructed space:

• Empty the room, move furniture or remove individual pieces, as the early editing demo demonstrates.
• Repaint walls, floors, ceilings and individual objects.
• Switch to a top-down floor-plan view.
• Hover over the Style menu to preview room presets.
• Upload wallpaper for a wall or object, and change object materials.
• Press Render to turn the current 3D perspective into a photorealistic image, which Levels initially timed at about 20 seconds.

Object-level editing is the strongest addition.

The browser viewer used Three.js even when Blender generated the scene. Levels’ subsequent rendering experiments included:

• WebGPURenderer r187 with SSGI and SSR, which he said looked better.
• Lighting probes, suggested by @threejs and @mrdoob.

Probes store lighting information used to approximate illumination on objects, according to the Three.js documentation.

MengTo published a separate apartment-recreation tutorial using Three.js, Opus 5.5 and Fable 5.2. He said he had not used exact measurements and that doing so would have taken longer.
