Hello, I'm Shihan Fang. 👋

Game Engine Developer | Graphics Programmer | Tech Enthusiast

Welcome to my GitHub! I am deeply passionate about pushing the boundaries of real-time rendering and system performance. I love solving complex problems at the intersection of hardware and software.

💻 Featured Projects

⚙️ Game Engine Development

  • Lumina Engine 🚧 In Development
    • A custom game engine focused on high-performance rendering pipelines and core systems architecture.
    • Tech: C++ Engine Architecture Modern Graphics API

🍎 Computer Graphics & Rendering

  • ShadowMapping Software Rasterizer

    • A CPU-based 3D software rasterizer built entirely from scratch without graphics APIs. Features two-pass Shadow Mapping, a custom linear algebra math library, and programmable shader simulation.
    • Tech: C++11 CMake Computer Graphics

  • CPU Monte Carlo Path Tracer

    • A physically based CPU path tracer implementing Monte Carlo integration, Importance Sampling (PDF), and BVH spatial acceleration for efficient global illumination. Supports participating media, Perlin noise, and PBR-like materials.
