FerrousGL is a simple-to-use Rust library that provides simple abstractions over OpenGL and GLFW for creating graphical applications and games easier. It offers a straightforward way to handle windows, rendering, shader, textures and meshes without having to be fluent in graphics programming.

The library is very simple-to-use: First you can make a window. This window serves as the foundation for rendering meshes (on the main framebuffer or a custom render texture), shaders and input.

⚠️ Version Warning: This project is currently in early development, so versions below 0.1.0 may not be backwards compatible to older beta versions.

Key features

• Windows: Windows are like modular bricks of a foundation, the library allows for simultaneous creation & deletion of windows and input! This allows for simple multi-window applications or debug views!
• Meshes: Meshes are simple-to-use and allow for custom vertex attributes.
• Shaders: You can load shaders from files or from code. There is support for uniforms and textures.
• Textures: The textures allow you to load images to use in shaders and there are also render textures for rendering to an off screen buffer!
• Hot-Shader-Reloading: Shaders are able to be reloaded at runtime, allowing for hot-shader-reloading.

The library is designed to be simple-to-use while providing enough flexibility for most graphics programming tasks. It handles much of the boilerplate OpenGL code while exposing many things needed for 2D/3D rendering.

How to run examples

1. Download the repository
2. Navigate into the repositories directory
3. Run cargo run --example to list all available examples
4. Run an example with cargo run --example particles --release to run it in release mode. Replace particles with the name of the example.

Example use cases

• Graphical applications such as drawing apps
• Games in 2D or 3D with custom engines
• Visualizations
• Learning OpenGL

How did this library come into existence? A friend once told me "Graphics programming is too hard; it's not worth getting into.", so FerrousGL was born. This library doesn't focus on being the most efficient (even tho I try to keep it quite fast), but it focuses on making OpenGL more accessible easily so you can write graphically powered software more easily!
