Sock Engine

A lightweight 3D game engine made with C++

Source Code

Overview

Sock Engine is a custom 3D game engine made with C++. The engine is primarily a learning project focused on understanding game engine architecture and graphics programming fundamentals. Currently, the engine is mostly just a glorified renderer with some UI controls for the scene, but I work on the engine whenever I'm not making games and it gets closer to the intended experience with every update.
