A Vulkan game engine in Rust. Playground for graphics experiments. 🐒
- Vulkan 1.3 🔺 - Dynamic rendering, Synchronization2, VMA integration, bindless textures
- Custom ECS 🧩 - Sparse set storage, query system, component derive macros
- Render graph 📊 - Resource lifetime management, automatic barrier insertion
- PBR materials 💎 - Hot reload support, template-based definitions
- WGSL shaders ✨ - Compiled via naga at runtime
- GLTF support 🦊 - Skeletal animation, PBR materials, background loading
- Editor UI 🖼️ - Declarative dockable panels, asset browser, entity inspector, transform gizmos, CodeEditor with syntect highlighting
- Bindless textures 🎨 - Single texture array for UI rendering, texture switching via vertex indices, no push descriptor overhead
- Text pipeline 🔤 - cosmic-text with HarfBuzz shaping, BiDi, CJK, word wrapping, font fallback; swash rasterization, etagere atlas packing, subpixel positioning
- GPU-instanced UI ⚡ - Instanced rendering (shared unit quad + per-instance data) replaces per-quad vertex emission; incremental Taffy layout caching via dirty flags

cargo run # Run the demo 🎮
cargo run -- -s # Limited frames (validation) ✅
cargo test # Run tests 🧪It sure is, I ain't got time to write all of this
This repo has become my playground for vibecoding to see how good or bad it can be.
