# 🔮 Image to 3D with [TripoSG](https://github.com/VAST-AI-Research/TripoSG)

## State-of-the-art Open Source 3D Generation Using Large-Scale Rectified Flow Transformers

<p style="font-size: 1.1em;">By <a href="https://www.tripo3d.ai/" style="color: #1E90FF; text-decoration: none; font-weight: bold;">Tripo</a></p>

## 📋 Quick Start Guide:
1. **Upload an image** (single object works best)
2. Click **Generate Shape** to create the 3D mesh
3. Click **Apply Texture** to add textures
4. Use **Download GLB** to save your 3D model
5. Adjust parameters under **Generation Settings** for fine-tuning

Best results come from clean, well-lit images with clear subject isolation. Try it now!

<p style="font-size: 0.9em; margin-top: 10px;">Texture generation powered by <a href="https://github.com/huanngzh/MV-Adapter" style="color: #1E90FF; text-decoration: none;">MV-Adapter</a> - a versatile multi-view adapter for consistent texture generation. Try the <a href="https://huggingface.co/spaces/VAST-AI/MV-Adapter-I2MV-SDXL" style="color: #1E90FF; text-decoration: none;">MV-Adapter demo</a> for multi-view image generation.</p>
