Favicon notify

Hack of the day from a few weeks back: show small notification bubble in the favicon. Check out the code at https://github.com/kig/faviconNotify and go to http://fhtr.org/faviconNotify for a demo.

Usage

  FaviconNotify.set(number);
  FaviconNotify.clear();

Longer example of use in HTML

  <html>
    <head>
      <link rel="icon" href="favicon.ico">
      <script src="faviconNotify.js"></script>
      <script>
        window.onblur = function() {
          FaviconNotify.set(1);
        };
        window.onfocus = function() {
          FaviconNotify.clear();
        };
      </script>
    </head>
  </html>

Updated Three.js deck

I updated the "Basics of Three.js"-presentation to work with the latest version of the library. My Google Developer Day "Introduction to WebGL"-presentation is also online, and updated to match the latest changes to Three.js.

In more detail, the changes were:
  • $FOO.addChild and $FOO.addLight were merged into a single method, $FOO.add
  • Camera was deprecated and split into a PerspectiveCamera and OrthographicCamera
  • Camera no longer has a target that it tracks, you need to use camera.lookAt(vec3) on every frame to accomplish that.
  • MeshShaderMaterial was deprecated and renamed to ShaderMaterial
  • material.ambient now needs an AmbientLight in the scene to work (AmbientLight color is multiplied by material.ambient in the shader)
  • ColladaLoader was renamed to THREE.ColladaLoader
