# OF<sup>3</sup>GS: <u>O</u>n-the-<u>F</u>ly <u>F</u>eed-<u>F</u>orward 3D <u>G</u>aussian <u>S</u>platting from Unposed Images
[Project Website](https://richardchen225.github.io/of3gs/) | [Paper](https://arxiv.org/abs/2606.03254) | [GitHub Repo](https://github.com/richardchen225/OF3GS_code)
This repository hosts the official OF3GS checkpoint.
## Model File
- `model.ckpt`: OF3GS checkpoint for inference and evaluation.
## Usage
Please see the GitHub repository for installation instructions, dataset preparation, and testing commands.
The checkpoint is expected to be used with the FreeStreamGS codebase by setting:
```bash
PRE_FREEGS_PATH=/path/to/model.ckpt
```
or by downloading this file into:
```text
weights/of3gs.ckpt
```
