How to use the "VSR WebGL Export" plug-in?
A demonstration video of how to use the WebGL Export plug-in can be found here.
What is WebGL?
WebGL is a Web standard for 3D graphics, which can be directly interpreted by Web browsers. It allows you to create 3D data that can be viewed, rotated and zoomed directly in the Web browser, without the need to install an additional program. A more technical description for developers can be found here.
Which browsers support WebGL?
The Internet Explorer needs a plug-in to run WebGL data. One possible plug-in for this is Google Chrome Frame. However, this plug-in currently seems to require a web hosted WebGL content to be opened first, before it can open locally stored HTML files. This may also be the reason why http://get.webgl.org does not recognize the full WebGL capability of Internet Explorer with this plug-in.
The currently supported browsers can also be checked here.
What does a "VSR WebGL Export" example look like?
An HTML page created with the "VSR WebGL Export" plug-in looks like this (plain picture, no active WebGL content).
What size are WebGL HTML pages allowed to have?
How to reduce the file size?
If your model contains surfaces (not only meshes), you can use less precise mesh settings in Rhino to reduce the file size ("Tools - Options - Document properties - Mesh"). Also keep in mind that textures can become pretty big when being exported as WebGL.
