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 glutin; extern crate libc; extern crate gl;

fn main() { let window = glutin::Window::new().unwrap();

unsafe { window.make_current() };

unsafe {
    gl::load_with(|symbol| window.get_proc_address(symbol));

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

while !window.is_closed() {
    window.wait_events();

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

    window.swap_buffers();
}

} ```

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

Win32

• You must call glFlush before swap_buffers, or else on Windows 8 nothing will be visible on the window

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.
