# Sapphire
Sapphire is a game engine developed in C++ using OpenGL. It started as a personal project to explore game engine architecture and learn how to manage a multi-system application. Inspired by The [Cherno's game engine series](https://www.youtube.com/playlist?list=PLlrATfBNZ98dC-V-N3m0Go4deliWHPFwT), this project has been a hands-on journey into graphics programming, rendering techniques, and engine development.
You can check out the presentation I made for this project [here](https://docs.google.com/presentation/d/1hBBXi7OgnB5CnnUq6ogenfiARTrwbtATjnQTT7INczE/edit?usp=sharing).
## Why I Built This
I wanted to understand how a game engine works under the hood while also tackling the challenges of structuring a multi-system application. Rather than focusing purely on the complexity of code, my goal was to design an engine that effectively integrates different components, such as rendering, scene management, and EditorUI.
## Development Journey
1. **Core Engine:** I began by implementing the core application that I could rely on to build the redenring features.
2. **Graphics Features:** I progressively added:
- Quad rendering
- Texturing & blending
- Batch rendering
- Frame buffers
3. **Lighting System:** I experimented with a simple shader-based lighting system to push my understanding of real-time rendering.
4. **Scene Management & Editor:** Currently, I am developing a scene management system and an editor to make the engine more practical for game development.
## Installation
To get started, clone the repository:
```sh
git clone https://github.com/Theo-Mestre/sapphire.git
```
Then, build the project using the `SetupWindows.bat` script located inside the `Scripts` folder.
