Lacuna Game Engine (LacunaGE) is a game engine / framework that I am working on in my spare time. I currently am mainly focusing on the rendering engine (which has a Vulkan, DX12 and a GNM implementation). Physics will be handled by a third-party library like Bullet3D or PhysX. Audio will initially not have an implementation since I am planning on exploring audio programming. The latest version of this engine is unavailable thanks to the Playstation specific code.
