# PreviewGaussianSplat - ComfyUI Built-in Node Documentation

> The PreviewGaussianSplat node displays a 3D gaussian splat file in a preview window without saving it to the ComfyUI output directory.

The PreviewGaussianSplat node displays a 3D gaussian splat file in a preview window without saving it to the ComfyUI output directory. It accepts a 3D model file in various gaussian splat formats, saves a temporary copy for previewing, and passes the model data through for further processing in the workflow.

## Inputs

| Parameter        | Description                                                                                                               | Data Type       | Required | Range                               |
| ---------------- | ------------------------------------------------------------------------------------------------------------------------- | --------------- | -------- | ----------------------------------- |
| `model_3d`       | A gaussian splat 3D file.                                                                                                 | FILE3D          | Yes      | splat<br />ply<br />spz<br />ksplat |
| `model_3d_info`  | Optional metadata information about the 3D model. When not connected, the node uses the model info from `viewport_state`. | LOAD3DMODELINFO | No       | -                                   |
| `viewport_state` | The current state of the 3D viewport, including camera and model information.                                             | LOAD3D          | Yes      | -                                   |
| `camera_info`    | Optional camera information for the preview. When not connected, the node uses the camera info from `viewport_state`.     | LOAD3DCAMERA    | No       | -                                   |
| `width`          | The width of the preview render in pixels (default: 1024).                                                                | INT             | Yes      | 1 to 4096                           |
| `height`         | The height of the preview render in pixels (default: 1024).                                                               | INT             | Yes      | 1 to 4096                           |

Note: When `camera_info` or `model_3d_info` are not provided, the node falls back to the camera and model information stored in `viewport_state`.

## Outputs

| Output Name     | Description                                                                                        | Data Type       |
| --------------- | -------------------------------------------------------------------------------------------------- | --------------- |
| `model_3d`      | The input 3D gaussian splat file, passed through unchanged.                                        | FILE3D          |
| `model_3d_info` | Metadata information about the 3D model, either from the input or derived from the viewport state. | LOAD3DMODELINFO |
| `camera_info`   | Camera information for the preview, either from the input or derived from the viewport state.      | LOAD3DCAMERA    |
| `width`         | The width of the preview render.                                                                   | INT             |
| `height`        | The height of the preview render.                                                                  | INT             |
