DOOM
This project is a first-person shooter game engine and a pseudo-3D rendering engine written in C. It serves as a software framework for rendering three-dimensional environments and managing entity physics.
The engine includes a networked multiplayer system designed to synchronize game state and player actions across a client-server network. It utilizes a portable codebase that allows game logic to be adapted across different operating systems and hardware architectures.
Core capabilities cover 3D game engine architecture, including spatial partitioning and depth-based rendering. The system also implements game physics simulation for entity movement, collision detection, and line-of-sight checks against environment geometry.
