## Overview

tinyGE is a small C++ graphics-engine library. Its exposed workflow is engine initialization, window creation, and event-driven ticking; rendering-related types provide meshes, shaders, textures, cameras, sprites, and object components. The sampled lifecycle implementation does not show a complete scene-rendering pipeline or connect those types to its tick loop, so the graph keeps those relationships separate. The README documents no capabilities beyond the project name; unsampled subsystem relationships are omitted rather than inferred.

Main entry points: [`tinyGE/include/core/object.h`](https://github.com/trevor-cmd-cmd/project/blob/main/tinyGE/include/core/object.h) (Objects), [`tinyGE/include/core/sprite.h`](https://github.com/trevor-cmd-cmd/project/blob/main/tinyGE/include/core/sprite.h) (Sprites), [`tinyGE/src/core/tinyGE.cpp`](https://github.com/trevor-cmd-cmd/project/blob/main/tinyGE/src/core/tinyGE.cpp) (Engine lifecycle), [`tinyGE/include/core/component.h`](https://github.com/trevor-cmd-cmd/project/blob/main/tinyGE/include/core/component.h) (Components)
