Utopian Engine
This project is developed to learn how renderers and game engines works as well as acting as a base for research/experimentation. The intention is to make my own games using it and also once more mature make it convenient for others to use as well.
It is written in C++ and uses Vulkan as the rendering API.

Building
Currently the project only runs on Windows.
Run git submodule update --init --recursive to checkout the required submodules.
Run ./generate_workspace.bat script to generate a Visual Studio 2019 solution.
If you want to generate a solution for another VS version run tools/premake5.exe manually.
Pre compiled libraries for MSVC x64 Debug and Release are included in the libs/ folder.
