in crpg there menu option where you can access to your equipment, item, skill, save your game etc. i wanted to ask, that if we created a 3d crpg game using opengl, and how to make the menu that i mentioned before appear. because what i know about opengl that once we initialize it. the what we see in our window is based on our glViewport(); so if someone pushin a button that will send message to the windows and... what should we code for that? sorry english is not my mother language. so if this is counfusing you, i''m sorry

You would want to draw the menu in ortho view (flat)

I''m just thinking, if you already have the code to do 3-d scenes, why not use them for the menu too...

To pick objects from the scene, look at Lesson 32

Ideas:
a 3-d person, a file cabinet nearby, a trophy on a table

Click on the 3-d person to get to the inventory scene.
Click on the file cabinet to get to the load/save scene.
Click on the trophy for skills scene.

Maybe the inventory scene is a dark room with each piece of equipment floating and rotating. Click on an item and a semi-transparent rectangle appears over it with information written about it.

Maybe the load/save scene is bunch of rotating books.

Maybe the skills scene is a room full of animated characters performing each skill over and over with a color-coded bar showing the amount of each skill or something.
