If you want to do some post-processing of .obj files, you might take a look at my "STOMP" utility (PC only)... it has an OpenGL 3D display and should read both PC and Mac formated files, reads 'fo' lines, reads relative vertex offsets, has features for scaling/mirroring/(re)generating normals and gives several options for output, including squishing and re-sorting of facets (by group or material, for example). So far, no one has bothered to give me any feedback on it, so I have to ASSUME it works well ;). The one issue that I know it has is related to .obj files where SOME faces are textures and SOME are not... the program currently expects all facets to be in the same format and will ignore/discard ones that are not (I am working on a fix for that). BTW, 'S.T.O.M.P.' sounds menacing, but it stands for "Spanki's Three-D Object Manipulation Program" (or something like that).
