Hi guys.

Question:

How me calculate face normals and vertex normals in each render? For algorithm back-face culling!

If you can please show on function in source code.

This is not really an OpenGL question. Try google

You're possibly heading down the wrong ally.

Read this thread (http://www.opengl.org/discussion_boards/ubb/Forum3/HTML/005877.html) and make sure you understand it.
