If you want an editor to try those .obj files on, you could download the free lite version of the DeleD 3d editor from http://www.delgine.com/. I believe it was written using Delphi actually

The direct link to the editor download page is http://www.delgine.com/index.php?filename=product_deled

You can download from the same site, an Obj 3d file importer/exporter plugin for the editor (http://www.delgine.com/plugins/viewPluginCategories.php).

It is a very nice free 3d editor program perhaps you could get some ideas from it

It allows editing of vertices/faces/polygons, etc.

PS. I even created a plugin for the program myself using Delphi (http://www.delgine.com/plugins/viewP...s&contentid=22)
