How To Create Holes In Object In Opengl?

[Nick]

I need to get a source-code or just good article of OpenGL program, where some object (sphere or cube) is "drilled". :) I searched all the Net but failed to find anything.

It's not possible to "drill" a basic primitive. You have to create your own object with the hole already in it.

Well, all right. How to drill a cube, constructed of 6 polyons. That will be OK?

EDIT: Although, it doesn't matter. I see you can't help.
