"content": "## Automate 3D Body Model Generation from Images Using Fal AI & Google Sheets\nThis workflow automates the process of **generating 3D human body models** (in `.glb` format) from **single image** using SAM-3D model. It operates by connecting a Google Sheet as a data source with the external AI processing API. \n\nSAM 3D allows for accurate 3D reconstruction of human body shape and position from a single image.\n\n### **How it works:**\n\nThis workflow automatically creates `.glb` 3D human body models from single images using SAM-3D API. It starts by fetching image URLs from a Google Sheet where the \u201c3D RESULT\u201d field is empty. Each image is sent to the API, which returns a `request_id` for job tracking. The workflow then polls the API at intervals to check job status, repeating until completion. When the model is ready, it retrieves the 3D file URL and downloads the `.glb` file. Finally, the workflow updates the corresponding Google Sheet row by writing the result URL to the \u201cIMAGE RESULT\u201d column, marking the process as complete.\n\n### **Setup steps:**\n\nClone the provided Google Sheet and add image URLs under \u201cIMAGE MODEL,\u201d leaving \u201cIMAGE RESULT\u201d empty. Connect n8n with Google Sheets using OAuth2 credentials for the **Get new image** and **Update result** nodes. Create an FAL.AI account to obtain an API key, then configure \u201cHTTP Header Auth\u201d credentials with `Authorization: Key YOUR_API_KEY_HERE` and assign them to all equest nodes. Verify each node\u2019s filters, JSON references, and completion checks. Finally, test the workflow manually with one image before enabling the schedule trigger for automated execution.\n\n\n"
