# webgl

[GopherJS](https://github.com/neelance/gopherjs) bindings for WebGL context.  

Supports a subset of webgl2: VAOs and instanced arrays.  Adding additional support is trivial and pull requests are welcome.

## Example

webgl_example.go:

```Go
package main

import (
	"github.com/gopherjs/gopherjs/js"
	"github.com/gopherjs/webgl"
)

func main() {
	document := js.Global.Get("document")
	canvas := document.Call("createElement", "canvas")
	document.Get("body").Call("appendChild", canvas)

	attrs := webgl.DefaultAttributes()
	attrs.Alpha = false

	gl, err := webgl.NewContext(canvas, attrs)
	if err != nil {
		js.Global.Call("alert", "Error: "+err.Error())
	}

	gl.ClearColor(0.8, 0.3, 0.01, 1)
	gl.Clear(gl.COLOR_BUFFER_BIT)
}
```
