I wrote a game in C++. now I am trying to export a blender file to C++. Anyone can teach me how to do it! 
the blend files contains a lot of data in binary format.
most of the data is useless for other programs.
you may want to export your models in any standard (text) formats.
there a loads python scripts for almost any format you like.
so all have to do then is write a parser in your C++ App. to read the data.
there is a freeware program “crossroads” which generates opengl C++ code
from 3d mesh data if this helps
