Hello Bemfarmer,

Yes for the browser. All runs very well with FireFox 25, no need the Chrome of Google.
But I advise you the Torch browser, it's the same browser here: http://www.torchbrowser.com/

An other link to make these 3d web experiences (all free but not good) : http://ts4.us/tools/3dviewer-flash.html

From Activeden, good, very small price, very fluid : http://activeden.net/item/3d-object-viewer/116372
