pacman.zig is a faithful recreation of the classic Pacman arcade game implemented in the Zig programming language. It uses the Sokol cross-platform libraries for graphics, audio, and input handling, allowing it to run as a native desktop application or be compiled to WebAssembly for browser play. The game implements all original Pacman mechanics including Pacman movement, ghost AI with distinct behaviors for each ghost, dot and pill eating, bonus fruits, sound effects, score tracking, and level progression. The architecture follows a monolithic design with clear separation of concerns into game state management, game logic, rendering, audio, and input systems. Despite being contained primarily in a single source file, the code is well-organized with distinct sections for different subsystems. The implementation demonstrates attention to detail in replicating the original game's behavior and performance characteristics.
NVIDIA Streamline is a middleware SDK that simplifies integrating NVIDIA graphics technologies—including DLSS (super resolution, frame generation, ray reconstruction), Reflex (low latency), NIS (image scaling), DeepDVC (dynamic contrast), and DirectSR—into DirectX 12, 11, and Vulkan games on Windows. It provides a unified API, a plugin-based architecture where each feature is a separate loaded module, and an interposer (hooking) layer that intercepts graphics API calls (DXGI, D3D12, Vulkan) to automatically inject features without requiring game engine modifications. The SDK includes a core infrastructure with parameter sharing, logging, thread management, OTA updates, security verification, and a compute abstraction layer. While primarily an application integration SDK, it is not a research project; all code is production-oriented middleware. The repository is well-structured with clear separation of concerns, but heavily depends on NVIDIA-specific SDKs (NGX, NVAPI, Reflex) and is Windows-only, limiting portability. Build system uses premake5 with a custom packman package manager.
This repository is a browser-based WebGL bird flight simulator (birds.cafe) built with Three.js, not a data engineering or research project. It contains no data ingestion pipelines, ETL processes, feature engineering, ML models, or analytical schemas. The codebase implements a real-time graphics simulation with procedural generation: Gerstner wave ocean rendering with custom vertex shaders, instanced cloud layers with billboard shaders, procedural island meshes, and a flocking system with two-segment wing animation (flap-gliding behavior). Weather presets (day, night, storm) define color/lighting/fog parameters with smooth lerp transitions. Wildlife (dolphins, whales, passing bird flocks) spawns procedurally near the player. Audio uses HTMLAudioElement loops from external CDN URLs. The project runs entirely client-side with no backend, database, or data processing layer. As a data engineering repository, it has no reusable data assets — the algorithms are graphics/game programming patterns (shader math, instanced rendering, animation systems) not data operations.
