Due to my ignorance, I did a google search with: "webgl 3d model viewer"
There are a few "how-to-do's," but they do not work with IE9, as far as I can tell...

"Note that you will need a WebGL-enabled browser, eg Chrome, Firefox, Safari 5, Opera 12."

"All you need is a browser that supports WebGL. (Sorry IE and iOS users.)"
