So yes, this is a bit OT, so please forgive me. I tried site-searching and then Googling first to no avail, so I thought I’d take it to some of the ATI developing proponents here.
With the recommendations from various normal-mapping tutorials posted on the OpenGL.org front page links lately, I’ve downloaded ATI’s NormalMapper tool.
Unfortunately, it requires objects to be in their NMF format. Though the zip file came with various converters from Maya, Max, etc. to NMF, I found no format specification. (If I was the kinda guy who could afford to use 3DS Max, would I have to be messing around with the simplistic command line utility that, well, happens to be free?)
Anybody know where I can find an NMF spec so I can write a converter for my files?

Yes. It is a good utility. And it certainly beats writing your own.

Well, yeah. I’m sure it is good, and that it does beat writing my own.
However, if I had >$1000 of cash lying around, I’d probably choose buying something like Crytek’s PolyBump over my current approach, i.e. spend time locating/researching decent free polycount reducing and normal map generating utilities, write functions to convert my models to and from format #1, write functions to convert my models to and from format #2, and step-by-step convert each model to the appropriate utility format, use the utility, convert back, and repeat.
Which reminds me, any of you guys worked enough with freeware poly reduction utilities enough to have any recommendations?

Yeah, but I’ve never been either fast or particularly good at interpreting other people’s code. Especially when it’s something like the code that comes with NormalMapper… there’s stuff like a complete vector math library rewritten as about a page and a half of #defined functions, etc.
I’ll do it if I have to, I was just wondering if any of you guys knew if such a spec existed somewhere, cause it would really save me some time.
We recently started using the following tool: http://www.soclab.bth.se/practices/orb.html
The artists seem to like it so far. And we will probably use it for all or game models.
Another option is just to make your own file reader that fills an NmRawTriangle array with the data from your files. Use the following header prototype:
Put it in SMDFileIO.cpp. Then you can just #define USE_SMD_FILES in the NormalMapper.cpp file (uncomment the line near the top of the file) and rebuild. It should then use the file reader you added.
