## Sparc3D

**Model ID:** `model_sparc3d`

**Capabilities:** `img23d`

**LLM Markdown:** <https://app.scenario.com/api/models/model_sparc3d/markdown>

| Parameter     | Type        | Required | Default | Min | Max | Allowed Values                   | Description                                                                                                                                     |

| `images`      | file\_array | Yes      | -       | -   | -   | -                                | Upload 1-4 images, starting with the front view. For multi-image input, you can optionally include back, left, and right views (in that order). |
| `requestType` | number      | No       | `3`     | -   | -   | `1`, `3`                         | Choose whether to generate just a mesh or a textured 3D asset                                                                                   |
| `resolution`  | string      | No       | `1024`  | -   | -   | `512`, `1024`, `1536`, `1536pro` | Controls the voxel resolution of the generated 3D asset. Higher values deliver more detail and cleaner topology.                                |
