# easy-3dgs

A Python library for 3D Gaussian Splatting, designed to be easy to use and extend.

## Features

- **Modular Pipeline:** The reconstruction process is broken down into a series of modular steps, including feature retrieval, pair generation, feature extraction, feature matching, reconstruction, and image undistortion.
- **Extensible:** Each step in the pipeline is designed to be easily replaceable with custom implementations.
- **HLOC-Based:** Leverages the power of Hierarchical Localization (HLOC) for robust and accurate 3D reconstruction.

## Getting Started

### Prerequisites

- Python 3.10 or later
- Git

### Installation

#### Install from PyPI
You can install the library directly from PyPI using pip:

```bash
pip install git+https://github.com/Jourdelune/easy-3dgs.git
pip install git+https://github.com/cvg/Hierarchical-Localization.git
```

#### Install from Source

1. **Clone the repository:**

   ```bash
   git clone --recursive https://github.com/Jourdelune/easy-3dgs.git
   cd easy-3dgs
   ```

2. **Install dependencies:**

   ```bash
   pip install -e .
   pip install git+https://github.com/cvg/Hierarchical-Localization.git
   ```

### Usage

The main entry point for the library is the `ReconstructionPipeline` class. Here's a simple example of how to use it:

```python
from pathlib import Path
from easy_3dgs.pipeline import ReconstructionPipeline
from hloc import extract_features, match_features

# Define paths
image_directory = Path("path/to/your/images")
output_directory = Path("outputs/reconstruction")

# Define configurations
retrieval_config = extract_features.confs["netvlad"]
feature_config = extract_features.confs["superpoint_aachen"]
matcher_config = match_features.confs["superpoint+lightglue"]

# Create and run the pipeline
pipeline = ReconstructionPipeline(
    retrieval_conf=retrieval_config,
    feature_conf=feature_config,
    matcher_conf=matcher_config,
    num_matched_pairs=5,
)
pipeline.run(image_directory, output_directory)
```
