@MartinSojka There is nothing inherently wrong about modifying the OBJ exporter to include additional data. It would be wrong if he provided the resultant file to someone else and told them it was in Wavefront OBJ format, but the assumption is he's using the file himself. The majority of graphics programs define their own proprietary formats for convenience, many of which I'd wager are modified versions of the OBJ standard. If you include the additional data behind # characters, standard OBJ loaders will ignore your custom data as comments and the end result is a 100% compliant OBJ file.

It's much more complex than OBJ and it allows more flexibility than one would reasonably need to use for a static model. If you need additional flexibility, maybe you should use a more popular file format with well-established parsers, such as COLLADA | |
| Jul 21, 2012 at 10:09 | comment | added | Engineer | It's wrong because OBJ is a fixed specification. Once you start changing the exporter to do extra stuff, it is no longer an OBJ exporter, it's something else. From there, it could turn into just about any multi-headed beast. Still, good answer, I'd never heard of PLY. | |

Also, .obj is one of the not so many topics for which the wikipedia entry is actually usefull: en.wikipedia.org/wiki/Wavefront_.obj_file | |
| Dec 20, 2011 at 14:33 | comment | added | Ravachol | Why is that a wrong way ? If he just takes the OBJ exporter to make his own, I really fail to see how that's "wrong". The wrong way is not doing any work because it is always the wrong way to someone. | |
| Dec 20, 2011 at 13:49 | comment | added | Martin Sojka | The wrong way is to change the OBJ exporter. Use the right tool for the job; if you want vertex colours, Wavefront OBJ obviously isn't the tool you want to use (or abuse). | |
