A modular C++20 game and graphics engine, layered from the operating system and GPU drivers to the application.

Public libraries sit around a private RHI and renderer.
Orange is private (vnerhi, vnegfx). Dotted is future work (vneanim, vneai, vnexr).

vnerhi (RHI) and vnegfx (renderer) are private. The modules around them are public and follow the same C++20 / CMake layout.
| Layer | Repository | Role |
|---|---|---|
| Visualization | vnescene | Cameras, lights, and GPU-friendly scene state |
| Visualization | vneinteraction | Camera manipulators and controllers |
| Visualization | vneio | Mesh, image, volume, font and video |
| Visualization | vneshaderc | Offline GLSL to SPIR-V / MSL / WGSL |
| Platform | vnewindow | Native windows (Win32, Cocoa, X11, Wayland, UIKit, Android, Web) |
| Platform | vneevents | Keyboard, mouse, touch, and window events |
| Core | vnemath | Vectors, matrices, geometry, graphics clip-space helpers |
| Core | vnelogging | Synchronous and asynchronous logging |
| Core | vneutils | CLI parsing and shared helpers |
| Core | vnecommon | Platform detection, macros, non-copyable bases |
- Single-purpose libraries — scene, I/O, windowing, math, and logging can be learned and tested on their own.
- GPU backends behind an RHI — application code does not talk to Vulkan, Metal, or WebGPU directly.
- Independent CI — each repository configures, builds, and tests with the same CMake pattern.

Platform and component requirements (code-first, with test/sample evidence):
vnedd — VertexNova Engine Design Documents
Two tiers: high-level system requirements and per-library component specs.
VertexNova is an educational and experimental project with a long-term goal. Testing meets a high standard. The stack is POC-ready, not production-ready.
