putting 3D Creo parts on a website

Hello Everyone,

I'm going to start building a  web site for our clients, and I'm looking to see if there's a simple solution or plugin to get Creo parts in 3D on the web.  We don't have Windchill, so any method involving that is out, and Creo View Express is a standalone only product, correct?

So, if you've done this, what have you used, 3d pdf, vrml, obj?

Thanks!
