# 🏠 InteriorGen3D
## Single 2D Interior Image → High-Quality Editable 3D Interior Scene
**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:
1. **Scene Understanding** — Depth Anything V2 + SAM2 + SpatialLM
2. **Room Structure** — Manhattan-world constrained wall/floor/ceiling meshes
3. **Object Generation** — Multi-view diffusion → TRELLIS SLAT → PBR textures
4. **Scene Composition** — Physics optimization + Gaussian splat preview
5. **Export** — GLB/FBX/OBJ/USDZ with scene hierarchy
## Model Comparison
| System | Geo Quality | Texture | Speed | Scene Understanding | Editability |
|--------|-------------|---------|-------|--------------------:|-------------|
| TRELLIS.2 | 9.5/10 | 9/10 | 3-60s | ❌ | ⭐⭐⭐ |
| Hunyuan3D-2.1 | 8/10 | 9.5/10 | 30-60s | ❌ | ⭐⭐ |
| SF3D | 7.5/10 | 7/10 | 0.5s | ❌ | ⭐⭐ |
| **InteriorGen3D** | 8/10 | 8/10 | 30s | ✅ | ⭐⭐⭐⭐⭐ |
## Usage
```python
from interiorgen3d.pipeline.main_pipeline import InteriorGen3DPipeline
from interiorgen3d.config.pipeline_config import PipelineConfig
config = PipelineConfig.for_rtx4090()
pipeline = InteriorGen3DPipeline(config)
pipeline.load_models()
result = pipeline.generate("living_room.jpg", output_dir="./output")
```
## Training Data
- **3D-FRONT**: 18,968 rooms with furniture arrangements
- **Structured3D**: 21,835 rooms with panoramic renders
- **SpatialLM-Dataset**: 54,778 rooms with structured annotations
- **Objaverse** (filtered): ~50K interior furniture objects
- **Hypersim**: 461 photorealistic interior scenes
