Luna Engine
Backend-agnostic real-time rendering engine supporting Vulkan and DirectX 12 backends, built from scratch with a HAL (Hardware Abstraction Layer) design for portability and extensibility.
Features
| Component | Description |
|---|---|
| Render Backend | Vulkan / DirectX 12 (swappable via HAL) |
| GPU Profiler | Frame timing and pipeline-stage attribution |
| Resource Management | Explicit memory, barriers, descriptor heaps |
| Isaac Sim Interop | Streaming simulation state into the renderer |
| Build System | Premake5 |
| Debug UI | ImGui integration |
Architecture
- HAL Design Pattern — graphics API calls abstracted behind a unified interface, enabling backend swap without touching render logic
- Render Graph — explicit dependency tracking between passes for automatic resource barrier insertion
- Explicit Memory Management — manual heap allocation, resource upload, and lifetime control on both DX12 and Vulkan
Motivation
Built as an open-source alternative to proprietary sim environments (Isaac SIM, etc.) for sensor simulation research, and as a portfolio demonstration of low-level GPU systems engineering.
