game made on top of custom vulkan engine

vvne

Project aims to recreate a very inspiring muv luv gif using subset of c++, SDL and vulkan.

Current preview (still a veeeery long road ahead)

Features

• Handmade gltf2.0 glb model importer (nodes, animations, skinning)
• Integrated imgui
• Support for both windows (mingw) and linux
• Custom memory allocators (host and device)
• PBR with IBL (huge thanks to Sascha Willems vulkan examples and https://learnopengl.com/PBR/Theory)
• Signed distance field font rendering
• Multithreaded rendering / job system
• Cascaded shadow mapping

TODO - engine

short distance goals:

• Shader preloading and reuse
• Particle system (engine boost effect)

long distance goals:

• Editor for level design
• Global illumination (got to understand spherical harmonics and light probes first)
• Occluders (AABB trees)
• Parallelized pipeline creation (postponed since now it takes ~50ms in non-parallel form)

TODO - game

short distance goals:

• Small AI horde patrol throughout level
• Maintenence create drop call
• Shooting and melee
• Height calculation rework

long distance goals:

• AI combat
• better model and animations (while only using keyframes from glb)

Dependencies

• GCC at least 8.1 (to support C++2a)
• SDL2 (any version with SDL_vulkan header)
• lunarg vulkan sdk

How to build?

1. Change include paths inside CMakeLists.txt to suit development environment
2. Change dll paths for SDL and vulkan
3. Change glslangvalidator inside 'shaders/make_shaders.bat/.sh'
4. Install 'hashlib' library for python in use
5. use scripts for shaders, cmake for game
6. run binaries inside 'bin' folder
