The WebGLRenderingContext interface provides an interface to the OpenGL ES 2.0 graphics rendering context for the drawing surface of an HTML <canvas> element.

To get an access to a WebGL context for 2D and/or 3D graphics rendering, call getContext() on a <canvas> element, supplying "webgl" as the argument:

var canvas = document.getElementById('myCanvas');
var gl = canvas.getContext('webgl');

Once you have the WebGL rendering context for a canvas, you can render within it. The WebGL tutorial has more information, examples, and resources on how to get started with WebGL.

Constants

See the WebGL constants page.

The WebGL context

The following properties and methods provide general information and functionality to deal with the WebGL context:

WebGLRenderingContext.canvas
A read-only back-reference to the HTMLCanvasElement. Might be null if it is not associated with a <canvas> element.
WebGLRenderingContext.commit()

Pushes frames back to the original HTMLCanvasElement, if the context is not directly fixed to a specific canvas.

WebGLRenderingContext.drawingBufferWidth
The read-only width of the current drawing buffer. Should match the width of the canvas element associated with this context.
WebGLRenderingContext.drawingBufferHeight
The read-only height of the current drawing buffer. Should match the height of the canvas element associated with this context.
WebGLRenderingContext.getContextAttributes()
Returns a WebGLContextAttributes object that contains the actual context parameters. Might return null, if the context is lost.

Examples

WebGL context feature detection

This example demonstrates how to detect a WebGL rendering context and reports the result to the user.

<p>[ Here would go the result of WebGL feature detection ]</p>
<button>Press here to detect WebGLRenderingContext</button>
body {
  text-align : center;
}
button {
  display : block;
  font-size : inherit;
  margin : auto;
  padding : 0.6em;
}
// Run everything inside window load event handler, to make sure
// DOM is fully loaded and styled before trying to manipulate it.
window.addEventListener("load", function() {
  var paragraph = document.querySelector("p"),
    button = document.querySelector("button");
  // Adding click event handler to button.
  button.addEventListener("click", detectWebGLContext, false);
  function detectWebGLContext () {
    // Create canvas element. The canvas is not added to the
    // document itself, so it is never displayed in the
    // browser window.
    var canvas = document.createElement("canvas");
    // Get WebGLRenderingContext from canvas element.
    var gl = canvas.getContext("webgl")
      || canvas.getContext("experimental-webgl");
    // Report the result.
    if (gl && gl instanceof WebGLRenderingContext) {
      paragraph.innerHTML =
        "Congratulations! Your browser supports WebGL.";
    } else {
      paragraph.innerHTML = "Failed to get WebGL context. "
        + "Your browser or device may not support WebGL.";
    }
  }
}, false);

The source code of this example is also available on GitHub.

Effect of canvas size on rendering with WebGL

With scissor() and clear() we can demonstrate how the WebGL drawing buffer is affected by the size of the canvas.

The size of the first canvas is set to the styled Element size, determined by CSS. This is done by assigning the width and height properties of the canvas to the values of the clientWidth and clientHeight properties, respectively.

In contrast, no such assignment is done for the second canvas. The internal width and height properties of the canvas remain at default values, which are different than the actual size of the canvas Element in the browser window.

The effect is clearly visible when using scissor() and clear() to draw a square in the center of the canvas, by specifying its position and size in pixels. In the first canvas, we get the desired result. In the second, the square has the wrong shape, size, and position.

<p>Compare the two canvases.</p>
<canvas>Your browser does not seem to support 
    HTML5 canvas.</canvas>
<canvas>Your browser does not seem to support 
    HTML5 canvas.</canvas>
body {
  text-align : center;
}
canvas {
  display : inline-block;
  width : 120px;
  height : 80px;
  margin : auto;
  padding : 0;
  border : none;
  background-color : black;
}
window.addEventListener("load", function() {
  "use strict"
  var firstCanvas = document.getElementsByTagName("canvas")[0],
    secondCanvas = document.getElementsByTagName("canvas")[1];
  firstCanvas.width = firstCanvas.clientWidth;
  firstCanvas.height = firstCanvas.clientHeight;
  [firstCanvas, secondCanvas].forEach(function(canvas) {
    var gl = canvas.getContext("webgl")
      || canvas.getContext("experimental-webgl");
    if (!gl) {
      document.querySelector("p").innerHTML =
        "Failed to get WebGL context. "
        + "Your browser or device may not support WebGL.";
      return;
    }
    gl.viewport(0, 0,
      gl.drawingBufferWidth, gl.drawingBufferHeight);
    gl.enable(gl.SCISSOR_TEST);
    gl.scissor(30, 10, 60, 60);
    gl.clearColor(1.0, 1.0, 0.0, 1.0);
    gl.clear(gl.COLOR_BUFFER_BIT);
  });
}, false);
