sketchfab 3D and javascript

Hi everyone! My first post on here and I hope someone can help.

I know I can bring in a 3d model from sketchfab.com via embedding code into a web object, but does anyone have any clues on how I could do this with javascript?

I'm attempting to control a 3d model in captivate, and I figured if I could get the model in to start with, I can get to grips with the SketchFab API.

I know this is a long shot, but if anyone could be of help that would be great!

Cheers,

Mark
