# [zopengl](https://github.com/zig-gamedev/zopengl)

OpenGL loader, bindings and optional wrapper for Zig.

Supports:

  * OpenGL Core Profile up to version 4.2

  * OpenGL ES up to version 2.0

## Getting started

Example `build.zig`:

```zig

pub fn build(b: *std.Build) void {

    const exe = b.addExecutable(.{ ... });

    const zopengl = b.dependency("zopengl", .{});

    exe.root_module.addImport("zopengl", zopengl.module("root"));

}

```

Now in your code you may import and use `zopengl`:

```zig

const zopengl = @import("zopengl");

pub fn main() !void {

    // Create window and OpenGL context here... (you can use our `zsdl` or `zglfw` libs for this)

    try zopengl.loadCoreProfile(getProcAddress, 4, 0);

    const gl = zopengl.bindings; // or zopengl.wrapper (experimental)

    gl.clearBufferfv(gl.COLOR, 0, &[_]f32{ 0.2, 0.4, 0.8, 1.0 });

}

fn getProcAddress(name: [:0]const u8) ?*const anyopaque {

    // Load GL function pointer here

    // You could use `zsdl.gl.getProcAddress() or `zglfw.getProcAddress()`

}

```
