help about mdl

Maybe it's not a good question~~
I try to write a map-editer like wc's editer, and I only finished somethings about terrain-tile and trees; now I want to import *.mdx/*.mdl into my opengl projects, but I amnot familiar with these file format ; I spent lots of time in searching documents in here, but found nothing about detailed docs of *.mdx/*.mdl format.

somebody can give me a hand? a link or a relative detailed document or a open code source about loading *.mdx/*.mdl, I really want to finish my owner map-editer, thanks a lot .

Have you tried google?

Bing!
