This is the original C source code for the Quake game engine, a landmark first-person shooter engine from the 1990s. It is a retro game engine that renders 3D environments and processes player input in real time using CPU-based software rendering rather than GPU acceleration. The engine supports networked multiplayer gameplay over LAN or internet connections and is designed to be moddable, allowing users to create and run custom game modifications and levels. The engine's architecture includes a Binary Space Partition tree for efficient world geometry organization and visibility determination
Quake-2 is a game engine designed for the development of first-person shooters and the rendering of three-dimensional environments. It provides the core framework for processing real-time physics and player input within interactive 3D spaces. The engine supports software extensibility, allowing for the direct modification of source code to change gameplay mechanics and engine behaviors. This makes it a resource for retro game engineering and the study of early 3D development techniques. Its technical capabilities include vertex-based software rendering, BSP-tree spatial partitioning, and PVS
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 a
Quake III Arena is a first-person shooter game engine and arena combat simulator. It consists of the original C++ game source code for a cross-platform 3D game designed to run on Windows, Linux, and Mac. The project provides the source code necessary to render a first-person shooter experience, focusing on player-versus-player battles in closed 3D environments. It serves as a resource for legacy game preservation and the study of early 3D game engine construction. The engine incorporates spatial partitioning, client-side prediction, and state synchronization to manage multiplayer networking
