How to change wavefront(.obj) file based on changes made by OpenGL's camera view?
I use OpenGL's mouse display to rotate the 3D model, after that I want to make the updates to my wavefront(.obj) file so that the next time it will directly show the view that I want. Is there any idea about how to update the .obj file?

Drawing VBOs in OpenGL not working
I'm writing a simple class that parses an OBJ and renders the obj after that. I've already written a method for drawing vertex arrays from RAM and I wanted to optimize it a bit (I read that using VBOs gets you x4 times the framerate!).
