This library is a part of Unrust, a pure rust native/wasm game engine. This library provides a native/wasm compatibility layer for following components :

• OpenGL API

When used in conjonction with uni-app, on native target, it provides an OpenGL 3.2+ or OpenGLES 2.0+ Core Profile context. On web target, it provides a WebGL 2.0 context where available, else a WebGL 1.0 context.

Usage

[dependencies]
uni-app="0.3.*"
uni-gl="0.3.*"

extern crate uni_app;
extern crate uni_gl;

fn main() {
    // create the game window (native) or canvas (web)
    let app = uni_app::App::new(uni_app::AppConfig {
        size: (800, 600),
        title: "my game".to_owned(),
        vsync: true,
        show_cursor: true,
        headless: false,
        resizable: true,
        fullscreen: false,
        intercept_close_request: false,
    });
    // retrieve the opengl context
    let gl = uni_gl::WebGLRenderingContext::new(app.canvas());
    // start game loop
    app.run(move |_app: &mut uni_app::App| {
        // do some openGL stuff
        gl.clear_color(0.0, 0.0, 1.0, 1.0);
        gl.clear(uni_gl::BufferBit::Color);
    });
}

Build

As web app (wasm32-unknown-unknown)

Install wasm32 target :

rustup target install wasm32-unknown-unknown

Install wasm-pack and npm

Compile the demo with

This creates a wasm package in examples/pkg

Run the demo with

cd www
npm install
npm run start
