I'm want to start 3D programming with OpenGL but I don't know how

You can start by following the tutorials provided at:

Best of luck,

If you want to get into 3D programming you may also want to review a few other things:
- Your C++ knowledge as 3D apps can get complicated quickly.
- Your math skills, especially in the areas of vectors and matrices. OpenGL handles a lot of your matrix stuff behind the curtain, but it helps to understand what it is doing a little bit. Vectors are extremely important however, especially when you want to do lighting effects.
- Abstract data types like trees and graphs (for things like space partitioning, scene graphs, etc).

The bottom line is, you should know your math very well. If you can't do math, then you will most likely have great difficulty with graphics.
