Model to coordinates

[t43m4n]

Is there a way to convert polygons that i made in a modelling program (blender) to coordinates? I'm programming something in openGL and would want to know if i can make my life easier instead of imagining all the points.

For example I create two buildings on blender using 2 polygons. And I'd want to get the coordinate of these polygons (x,y,z) so that it would be easier for me to program it into openGL.

I hope you understood that hehehehe.

Thanks
