Epsilon Engine

Official repository for Epsilon Engine. Epsilon Engine is a next-gen, multi-platform, general purpose game engine.

Epsilon Engine© is a multi-platform, next-gen, on-development engine especifically designed to build high quality games and simulations. It uses Vulkan (previously OpenGL© 4.5) capabilities to deliver stunning graphics with great real time performance. It has been under development since 2015, and has constantly been catching up with the latest realtime, 3D techniques.

Screenshots and more detailed information is available on my Webpage

Installers and binaries will be available soon

Dependencies

• GLM
• GLFW
• Soft OpenAL
• VMA
• Beacon
• nlohmann/json

Building

Windows

• You'll need a working C++ compiler, either MSVC (Visual Studio) or MSYS2 MinGW/Clang will work.
• LunarG's Vulkan SDK, which you can download here (be sure it's in the Path)
• CMake GUI (optional)

Clone the repo

git clone https://github.com/ImanolFotia/Epsilon-Engine.git

cd Epsilon-Engine

git submodule init

git submodule update --remote

Build

Now you can either configure your project using CMake or CMake-GUI if you are using MinGW, or open Visual Studio IDE and open the project as "CMake Project"

Be careful, Visual Studio might decide that the primary project is 'EpsilonSharp.sln', this incorrect, as this is an Editor module, choose Epsilon.dll instead.

Linux

• You'll need to install LunarG's Vulkan SDK, which you can download here (be sure it's in the Path)

Clone the repo

git clone --recursive https://github.com/ImanolFotia/Epsilon-Engine.git

cd Epsilon-Engine
