Galaxy Engine is a free and open source project made for learning purposes by NarcisCalin. It is made with C++ and it is built on top of the Raylib library.

Galaxy Engine uses libraries from the FFmpeg project under the LGPLv2.1

The entire UI is made with the help of the Dear ImGui library.

Special thanks to Crisosphinx for helping me improve my code.

Special thanks to SergioCelso for making the learning process a little easier and also for helping me implement the initial version of the Barnes-Hut quadtree.

Special thanks to Emily for helping me on multiple occasions, including setting up the CMake configuration and assisting with various parts of the project.

Features

INTERACTIVITY

Galaxy Engine was built with interactivity in mind

SPH FLUID PHYSICS

REAL TIME PHYSICS

Thanks to the Barnes-Hut algorithm, Galaxy Engine can simulate tens or even hundreds of thousands of particles in real time

RENDERING

HOW TO INSTALL

• Download the latest release version from the releases tab and unzip the zip file.
• Run the executable file inside the folder.
• (Currently Galaxy Engine binaries are only available on Windows)

IMPORTANT INFORMATION

• Galaxy Engine releases might get flagged as a virus by your browser or by Windows Defender. This is normal. It happens mainly because the program is not signed by Microsoft (Which costs money). If you don't trust the binaries, you can always compile Galaxy Engine yourself

HOW TO BUILD

Dependencies

• CMake: On Windows, you can install it from their website or the Chocolatey cmake package, and on Linux you can install the cmake package with your package manager.
• A C++ compiler: Any compiler is probably gonna work, but Clang is recommended as it's known to produce a faster binary than GCC for this project.

• Clang: On Linux, you may install the clang package from a package manager. On Windows, it can be installed from their website, the Chocolatey llvm package, or from the Visual Studio Installer:

  

Basic instructions

These instructions assume you have already met the above requirements.

• Clone or download this repo
• Build the project with CMake
• After doing this you should have the executable file inside the build folder
• The last step is running the executable file from the same working directory as the "Textures" folder (otherwise the particles won't be visible). This applies to the "Shaders" and "fonts" folder as well
