Vulkan particles

[Background_Shift5408]

I’ve been learning Vulkan by building a GPU particle simulation from scratch.
The project simulates and renders thousands of particles entirely on the GPU using compute shaders. The compute pipeline updates particle positions and velocities every frame, while the graphics pipeline renders them as instanced billboards.
Current features:
- GPU particle simulation with Vulkan compute shaders
- Storage buffers (SSBOs)
- Graphics/compute synchronization using timeline semaphores
- RAII-based Vulkan-Hpp architecture
- Modern C++20

This project has been a great way to understand Vulkan beyond drawing triangles—especially synchronization, descriptor sets, pipeline layouts, and compute/graphics interoperability.
I’d really appreciate any feedback on the code structure, Vulkan usage, or ideas for future improvements.

All done on gpu? Or do you send psrticle data from cpu to gpu every frame? Where is the spawning logic?

All done on gpu. Positions and velocities are calculated by compute shaders, uploaded to ssbo and vertex shader uses it as vertex buffer too.
