# LoGeR: Long-Context Geometric Reconstruction with Hybrid Memory

This repository contains the reimplemented model checkpoints for **LoGeR**, as presented in the paper [LoGeR: Long-Context Geometric Reconstruction with Hybrid Memory](https://huggingface.co/papers/2603.03269). 

LoGeR processes long video streams in chunks with a hybrid memory design to improve large-scale geometric reconstruction quality and consistency.

## Checkpoints

We provide two main pre-trained models. To use them, please clone the [corresponding GitHub repository](https://github.com/Junyi42/LoGeR) and place the downloaded `.pt` files in your local `ckpts/` directory as follows:

- `ckpts/LoGeR/latest.pt`
- `ckpts/LoGeR_star/latest.pt`

### Download Commands

You can download the weights directly via `wget`:

```bash
# Download LoGeR
wget -O ckpts/LoGeR/latest.pt https://huggingface.co/Junyi42/LoGeR/resolve/main/LoGeR/latest.pt?download=true

# Download LoGeR_star
wget -O ckpts/LoGeR_star/latest.pt https://huggingface.co/Junyi42/LoGeR_star/latest.pt?download=true
```

## Usage
For detailed instructions on installation, running demos, and evaluation, please refer to the main [GitHub repository](https://github.com/Junyi42/LoGeR).
