gl

==

[![Go Reference](https://pkg.go.dev/badge/github.com/goxjs/gl.svg)](https://pkg.go.dev/github.com/goxjs/gl)

Package gl is a Go cross-platform binding for OpenGL, with an OpenGL ES 2-like API.

It supports:

- **macOS**, **Linux** and **Windows** via OpenGL 2.1 backend,

- **iOS** and **Android** via OpenGL ES 2.0 backend,

- **Modern Browsers** (desktop and mobile) via WebGL 1.0 backend.

This is a fork of golang.org/x/mobile/gl package with [CL 8793](https://go-review.googlesource.com/8793)

merged in and Windows support added. This package is fully functional, but may eventually become superceded by

the new x/mobile/gl plan. It will exist and be fully supported until it can be safely replaced by a better package.

Installation

------------

```sh

go get github.com/goxjs/gl

```

Usage

-----

This OpenGL binding has a ContextWatcher, which implements [glfw.ContextWatcher](https://godoc.org/github.com/goxjs/glfw#ContextWatcher)

interface. Recommended usage is with github.com/goxjs/glfw package, which accepts a ContextWatcher in its Init, and takes on the responsibility

of notifying it when context is made current or detached.

```Go

if err := glfw.Init(gl.ContextWatcher); err != nil {

	// Handle error.

}

defer glfw.Terminate()

```

If you're not using a ContextWatcher-aware glfw library, you must call methods of gl.ContextWatcher yourself whenever

you make a context current or detached.

```Go

window.MakeContextCurrent()

gl.ContextWatcher.OnMakeCurrent(nil)

glfw.DetachCurrentContext()

gl.ContextWatcher.OnDetach()

```
