# 4RC

[Project Page](https://luo-yihang.github.io/projects/4RC/) | [Arxiv](http://arxiv.org/abs/2602.10094) | [GitHub](https://github.com/Luo-Yihang/4RC)

This repo contains the pretrained weights for *4RC: 4D Reconstruction via Conditional Querying Anytime and Anywhere*.

*4RC (pronounced "ARC") enables unified and complete 4D reconstruction via conditional querying from monocular videos in a single feed-forward pass.*

## Usage

To load the model:
```python
import torch
from arc.models.arc.arc import Arc

device = "cuda" if torch.cuda.is_available() else "cpu"
model = Arc.from_pretrained("Luo-Yihang/4RC_geofinetune").to(device)
model.eval()
```
Please refer to our [repo](https://github.com/Luo-Yihang/4RC) for more details on loading and inference.
