Sliverlight.WebGL is a C#/.NET wrapper for in-browser access to WebGL functionality using Silverlight 5.

• Create 3D web browser applications using Silverlight plugin on Windows and Mac OSX.
• Easily port existing WebGL JavaScript code to Silverlight.
• Enable C# developers to put cross platform 3D applications in a web browser.

• Cannot use as a Silverlight Control and mix with other Silverlight controls.
• Cannot hide Silverlight control, it must be visible somewhere even if only 1x1 pixels.
• Cannot be used for out-of-browser 3D applications.
• Cannot show file:// URL based textures in IE9 or Chrome, but Firefox works OK.

The HTML5 canvas has a WebGL context on recent releases of Firefox, Chrome and Safari, and it can be faked on Internet Explorer with a plugin. The Silverlight HTML Bridge allows typesafe wrappers to be created around this JavaScript API so your application/game loop can be written and compiled in C#/VB.NET with the 3D being fully hardware accelerated
by the WebGL support in the browser.

Here's an example WebGL called from the C# wrapper:

public void clearColor(GLclampf red, GLclampf green, GLclampf blue, GLclampf alpha) {
    Invoke("clearColor", red, green, blue, alpha);
}

• Install the Runtime and Developer Requirements

• Download the latest source code from Silverlight-WebGL from GitHub. On Windows I used TortoiseGit following these instuctions.

• Open up the solution file LearningWebGL/LearningWebGL.sln in Visual Web Developer 2010 Express (it's free).

• Press Start Debugging (F5).

• Edit App.xaml.cs and change Lesson03 in this method to select a different lesson to view:

    private void Application_Startup(object sender, StartupEventArgs e) {
        this.RootVisual = new Canvas();
        new Lesson03() { Id = "Lesson" };
    }
  

• Silverlight 5
• WebGL enabled browser:
  • Internet Explorer via IEWebGL (tested in IE9 32-bit)
  • Firefox (tested in 10.0.2)
  • Chrome (tested in 17.0.963.79 m)
  • Safari on OSX (not tested yet)

• Microsoft Visual Web Developer 2010 Express
• Microsoft Silverlight 5 SDK

• The source code for Silverlight.WebGL is released under the MIT License.
• The source code for the LearningWebGL samples is ported from the original JavaScript WebGL samples on the Learning WebGL website which is largely based on the Nehe OpenGL Tutorials samples.
• The source code for GlMatrix is ported from the original JavaScript gl-matrix.js library by Brandon Jones.
• The iPhone graphic used in the sample pages is taken from openclipart.org by Ben Bois.
• The Silverlight.js file is the standard script from Microsoft.
• The WebGLHelper.js file is from IEWebGL to allow loading of their plugin for internet explorer, or the built-in WebGL if it's available.

• Fill in missing implementations of WebGL methods.
• Port the remaining samples from Learning WebGL.
• Test on Mac OSX in Safari, Chrome and Firefox and add browser matrix to this README.md file.
