InteriorGen3D is a production-grade AI system that converts a single interior photograph into a fully editable, photorealistic 3D scene. Unlike existing image-to-3D models (TRELLIS, Hunyuan3D-2, TripoSR) which are object-centric, InteriorGen3D is specialized for room-scale interior reconstruction with semantic decomposition.

✨ Key Features

🎯 Interior-Specialized: Trained on 3D-FRONT + Structured3D room data
🪑 Semantic Decomposition: Each furniture piece is a separate, editable 3D object
🏗️ Physics-Consistent: Manhattan-world geometry, gravity-aware placement
🎨 PBR Materials: Albedo + metallic + roughness maps
📦 Multi-Format Export: GLB, FBX, OBJ, USDZ
🔄 Editable: Move, rotate, delete, replace individual objects
💡 Relightable: Change environment lighting without re-generation
🚀 Fast: <30s on A100, <60s on RTX 4090

Architecture

5-Stage Pipeline:

Scene Understanding — Depth Anything V2 + SAM2 + SpatialLM
Room Structure — Manhattan-world constrained wall/floor/ceiling meshes
Object Generation — Multi-view diffusion → TRELLIS SLAT → PBR textures
Scene Composition — Physics optimization + Gaussian splat preview
Export — GLB/FBX/OBJ/USDZ with scene hierarchy
