glutin - OpenGL, UTilities and INput

Alternative to GLFW in pure Rust.

toml [dependencies] glutin = "*"

Documentation

Try it!

bash 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.

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

```rust extern crate gl; extern crate glutin; extern crate libc;

fn main() { let eventsloop = glutin::EventsLoop::new(); let window = glutin::WindowBuilder::new() .withtitle("Hello, world!".tostring()) .withdimensions(1024, 768) .withvsync() .build(&eventsloop) .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.
