# Light LAS (LLAS)

A simple, header-only, las-format file reader.

## Features

- Header-only

- Only used STL libraries

- Compatible with v1.2/v1.3/v1.4 LAS format (PointDataRecordFormat: 0 to 4)

- Read 33M points in 2 seconds

## Usage

You only have to include `include/llas.hpp` file.

## Example

```cpp

#include "llas.hpp"

int main(int argc, char** argv) {

    // Read .las file

    const auto lasData = llas::read("sample.las");

    if (lasData != nullptr) {

        // You can access to Public Header.

        const auto systemIdentifier = lasData->publicHeader.systemIdentifier;

        

        // You can easily get point coordinates as linear vector.

        const auto pointCoords = data->getPointCoords();

        // You can easily get point colors as linear vector.

        const auto pointColors = data->getPointColors();

    }

}

```
