glutin - OpenGL, UTilities and INput

Alternative to GLFW in pure Rust.

[dependencies]
glutin = "*"

Documentation

Try it!

git clone https://github.com/tomaka/glutin
cd glutin
cargo run --example window

Usage

Glutin is an OpenGL context creation library and doesn't directly provide OpenGL bindings for you.

[dependencies]
gl = "*"
libc = "*"

extern crate gl;
extern crate glutin;
extern crate libc;

fn main() {
    let events_loop = glutin::EventsLoop::new();
    let window = glutin::WindowBuilder::new()
        .with_title("Hello, world!".to_string())
        .with_dimensions(1024, 768)
        .with_vsync()
        .build(&events_loop)
        .unwrap();

    unsafe {
        window.make_current()
    }.unwrap();

    unsafe {
        gl::load_with(|symbol| window.get_proc_address(symbol) as *const _);

        gl::ClearColor(0.0, 1.0, 0.0, 1.0);
    }

    let mut running = true;
    while running {
        events_loop.poll_events(|event| {
            match event {
                glutin::Event::WindowEvent{ event: glutin::WindowEvent::Closed, .. } => {
                    running = false;
                },
                _ => ()
            }
        });

        unsafe {
            gl::Clear(gl::COLOR_BUFFER_BIT);
        }

        window.swap_buffers().unwrap();
    }
}

Note that glutin aims at being a low-level brick in your rendering infrastructure. You are encouraged to write another layer of abstraction between glutin and your application.

Platform-specific notes

Android

• To compile the examples for android, initialize the submodules, go to deps/apk-builder/apk-builder and run cargo build, then go back to glutin and call ANDROID_HOME=/path/to/sdk NDK_HOME=/path/to/ndk NDK_STANDALONE=/path/to/standalone cargo test --no-run --target=arm-linux-androideabi

X11

• The plan is that glutin tries to dynamically link-to and use wayland if possible. If it doesn't work, it will try xlib instead. If it doesn't work, it will try libcaca. This is work-in-progress.
