Another beginner question here 
I have a problem with the near clipping. I suspect that this problem has a correpond with perspective calculation. I usually calculate the perspective viewing on a resize function like this:
gluPerspective( 45.0, width/height, 1.0, 1000.0);
The problem is that the near clipping plane seems to be in front of the viewer, so, I can’t get the objects a closer look, like i can get in the games.
Sorry if you confused with my English.
Thanks! (^_^)
If the near clip plane is too far away, why don’t you move it closer?

IMO your near plane distance is fine. Pulling it in will eventually create nasty z buffering problems.
If you want a genuine ‘zoom’ function like in Quake 3 (just one game … ), that’s done by narrowing the fov. Ie, instead of 45 degrees, you go down to 12.5 degrees. For a smooth transition this must be animated, of course.
