Interior AI adds 3D floor plan walkthroughs

Automating 2D-to-3D spatial reconstruction from sparse floor plans has long been a bottleneck in proptech, requiring manual CAD modeling or expensive LiDAR scans. If solo indie hackers can ship functional browser-based WebGPU walkthroughs from a single blueprint image, traditional architectural visualization workflows face rapid commoditization.

• –Sparse input challenge: Floor plans lack height, texture, and furniture data, forcing the diffusion model to hallucinate cohesive architectural elements like windows and plumbing fixtures from minimal 2D outlines.
• –Client-side WebGPU acceleration: Leveraging Three.js with WebGPURenderer, screen space indirect lighting (SSGI), and screen space reflections (SSR) brings near-path-traced fidelity directly into the web browser without heavy server-side streaming costs.
• –Commoditizing virtual staging: Real estate staging typically costs hundreds of dollars per listing; turning static blueprints into navigable 3D models in minutes will significantly undercut manual 3D modeling agencies.
• –Current rough edges: As Levels noted, granular details like bathroom fixtures and complex sliding glass doors still degrade into simple geometric approximations, showing that CAD-level precision remains an open challenge.
