Usage as Library:

For Primitives

let rectangle = &mut Rectangle::new(200 //width, 
                                    200, // height
                                    "<path-to-glsl-shader>.shader");
'render: loop { 
    rectangle.attach(&gl);

    if window.resized == true {
        rectangle.window_resize(draw_size,size);
    }

    if key == "space" {
        rectangle.move_model(0,2.0,0.0);
    }
    rectangle.render(&gl);
}
rectangle.detach(&gl);

For Shaders

Note: Automatically adds GLSL version.

let shaders = ShaderData::new(source);

let shader_sources = [
    (VERTEX_SHADER_INT, shaders.vertex_shader.source),
    (VERTEX_SHADER_INT, shaders.fragment_shader.source),
];

Run with glfw

cargo run
cargo run --example glfw

Run with sdl2

cargo run --features sdl2

Setting up SDL2

macOS

Homebrew

On macOS, it's a good idea to install these via [homebrew][homebrew].

brew install sdl2

In recent versions of Homebrew, the installed libraries are usually linked into $(brew --prefix)/lib. If you are running an older version, the symlink for SDL might reside in /usr/local/lib.

To make linking libraries installed by Homebrew easier, do the following for your respective shell.

Add this line to your ~/.zshenv or ~/.bash_profile depending on whether you use ZSH or Bash.

export LIBRARY_PATH="$LIBRARY_PATH:$(brew --prefix)/lib"
