Modern Vulkan Game Engine

A game engine using modern vulkan techniques such as descriptor buffers, dynamic rendering and pipeline state-less rendering using VK_EXT_shader_object.

Engine Standouts

BBFramework, my custom framework to replace most of the STL

My own framework to replace parts of the STL to learn how and why it works. At times adjusting it to exactly what I need. Most data containers and cross-platform code comes from here. The base bones of the project. This project has a modified version of the BBFramework and is consindered to be the most up to date.

Tight memory control

Most if not all memory is managed via memory arena's, which are linear allocators with debug functionality to track memory usage. There are memory interfaces for freelists, but the underlying memory comes from a linear allocator.

Multiple scenes with async updating

The engine is made to support multiple scenes. With the image above you can see the the showcase rendering scene, and a game scene with a generated "dungeon" layout. These scenes can be updated async and you can have multiple of these scenes.

Custom math library

In order to learn the underlying math I have implemented most math functions and primitives myself. Pure for learning. All scenes handle their own input events.

ECS - WIP

The engine's internals will be using an ECS system per scene. This will simplify the scene rendering a whole lot.
