Floor Plan to 3D Interior Design Tool

A single-file HTML interior design tool generated from a floor plan. The 2D plan recreates walls, doors, and windows to scale and calculates room areas automatically. Furniture can be dragged, rotated, and snapped to walls, and the tool supports measuring, altering non-load-bearing walls, and changing floor materials. It transitions smoothly into a Three.js 3D bird's-eye view and first-person walkthrough. The screen recording runs about 33 seconds, suitable for short videos demoing home design tools or AI apps.
