Hi,

Being new to 3D programming, and currently in the process of developing
my first engine, could somebody please advise me if it is possible to
minimize the volume of my calculations by automatically eliminating
objects which are obviously not visible due to distance.

I am currently checking the visibility of every object in my world
space, and although quicker than pushing every object into the rendering
pipeline, it still requires unnecessary processing time.  Is there
anyway, using some kind of virtual grid maybe, I can ignore those
objects which are definitely too far away to be visible.

Any help you can give would be greatly appreciated.
