After answering several time very similar questions on web forums, you usually get tired and don't always come up with an answer that really educates people.

The one that was always coming back is the one about Z-buffering artifacts, missing objects and the like. So instead of rehashing incomplete answers ("Move your near plane farther"), I'd rather have a comprehensive answer people can refer to and if they're really interested they can take a look at the math to better decide themselves. So it's not really your typical FAQ as it doesn't answer a question and probably gives you more than what you asked for.

But anyway you can take a look at it here : The depth buffer the gritty details.
