what was the name of the plugin or even the file format for 3d studio that exported models and meshes to opengl format in c++ code?

Display List? I know you can save as a .3DS and then load that in something like 3D Explorer (now known as Deep Exploration I think) to create a display list. In fact ,that app will even make a complete app around the c++ code if you want it to.

Edit: Gah! Just checked and I don't think they do a trial version anymore. Sorry.

the one i was looking for output information similar to this:

float Box_Vertices[] = {0,0,0,               1,0,0,               ...};int Box_Faces[] = {0,1,2,                   ...};//it also output normals, and texture coordinates

Yeah, thats pretty much what a display list looks like.

Try heading over to http://www.maxplugins.de/ and search through their database as I found a display list exporter for version 7, not sure which version you have.
