# Oreon Engine (Java - OpenGL/Vulkan)

Welcome to the Cross-Platform Java 3D Engine.
OpenGL and Vulkan Binding for Java is done  [LWJGL 3](https://www.lwjgl.org/).

## Build Manual
* Oreon Engine project uses [lombok](https://projectlombok.org/).
  Please download the latest [release](https://projectlombok.org/download) of lombok and run the .jar to install lombok plugin into Eclipse.

* Getting started guide for Eclipse available [here](http://fynnfluegge.github.io/oreon-engine/_navigation/Getting_Started.html).

## Example OpenGL Demo
