## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.


### Input Schema

The API accepts the following input parameters:


- **`mesh_url`** (`string`, _required_):
  URL of the input 3D model to remesh. Supported formats: GLB, OBJ, FBX, STL (max 150MB).
  - Examples: "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb"

- **`quad`** (`boolean`, _optional_):
  Generate quad (4-sided) mesh topology instead of triangles. Forces FBX output. When enabled and 'face_limit' is unset, 'face_limit' defaults to 10000.
  - Default: `false`

- **`face_limit`** (`integer`, _optional_):
  Target face count of the remeshed model. Range 500-20000 (500-10000 when 'quad' is true). If unset, the model determines the count adaptively.
  - Range: `500` to `20000`

- **`bake`** (`boolean`, _optional_):
  Bake textures onto the remeshed model during generation. Default value: `true`
  - Default: `true`

- **`part_names`** (`list<string>`, _optional_):
  Optional list of part names (as returned by a prior mesh segmentation) to preserve as separate parts while remeshing.
  - Array of string



**Required Parameters Example**:

```json
{
  "mesh_url": "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb"
}
```

**Full Example**:

```json
{
  "mesh_url": "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb",
  "bake": true
}
```


### Output Schema

The API returns the following output format:

- **`model_mesh`** (`File`, _required_):
  Generated 3D model file. May be GLB or FBX depending on Tripo output.

- **`model_urls`** (`ModelUrls`, _required_):
  URLs for different 3D model variants.

- **`rendered_image`** (`File`, _optional_):
  Preview render of the generated 3D model.



**Example Response**:

```json
{
  "model_mesh": {
    "url": "",
    "content_type": "image/png",
    "file_name": "z9RV14K95DvU.png",
    "file_size": 4404019
  },
  "model_urls": {}
}
```


## Usage Examples

### cURL

```bash
curl --request POST \
  --url https://fal.run/tripo3d/tripo/remesh \
  --header "Authorization: Key $FAL_KEY" \
  --header "Content-Type: application/json" \
  --data '{
     "mesh_url": "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb"
   }'
```

### Python

Ensure you have the Python client installed:

```bash
pip install fal-client
```

Then use the API client to make requests:

```python
import fal_client

def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "tripo3d/tripo/remesh",
    arguments={
        "mesh_url": "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb"
    },
    with_logs=True,
    on_queue_update=on_queue_update,
)
print(result)
```

### JavaScript

Ensure you have the JavaScript client installed:

```bash
npm install --save @fal-ai/client
```

Then use the API client to make requests:

```javascript
import { fal } from "@fal-ai/client";

const result = await fal.subscribe("tripo3d/tripo/remesh", {
  input: {
    mesh_url: "https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Models/master/2.0/DamagedHelmet/glTF-Binary/DamagedHelmet.glb"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);
```
