Vulkan 2D Engine

Trying to learn Vulkan and Haskell hand in hand by doing a 2D engine.

How to

Compile the shaders, generate the atlas and run:

./run.sh

Compile the shaders:

./compile_shaders.sh

Generate the atlas

./generate_atlas.sh

TODO (doubling as a roadmap)

• Separate vertex buffer
• Sepaerate sempaphores per frame
• Use inflight frame with proper flow
• More than one in-flight frame
• Proper synchronization between frames
• Some memory is not properly freed before vulkan instance is destroyed
• Just use VMA
• Basic texture support
• Make the use of required feaures explicit
• Multiple sprites using different textures in one frame
• Use a texture atlas probably? Not sure yet
• Investigate sampler2DArray
• Sprite back-to-front sorting
• Alpha blending?
• Generate Vertex and Index buffers per frame
• Maybe images from the same buffer as well
• Basic static (no animation) sprite
• Sprite bacthing
• Bindless textures
• Buffer device addresses
• GPU driven rendering (DrawIndirect, etc)
• Basic DearImGUI integration
• Somewhat model a single moving light source
• Use normal maps on the static sprite to intract with the light sources
• Use specular maps for more realism
• Think about bloom and glow effects
• Suuport multiple light sources
• 2D global illumination
