it's pretty good, I think it's well known amonst Poser users. Poser uses OBJ files for geometry.

Should be quite useful for Bryce and other users working with OBJ files.

There's also perhaps MooTools 3D Photo Browser for 3D users.

Not sure right off the top of my head how they compare, if at all.

Check alkso for converters in www.thebest3d.com - some converters have good set of browsing tools and might be useful too for what you need. One I would check into is Myriad or another product from the same company. They're CAD oriented and do neat stuff like sectioning and converting many formats, presenting in 3D on the web and more. Informative Graphics is the company, from near Phoenix, AZ.
