Can someone explain Quake3 'hunk'?

Question

I read the source code and tried to research it on the Internet, but I hit the brick wall in terms of its full understanding.
I totally mean how it differs from the distribution of the zone?

Is “zone” used for small memory and “hunk” for larger files such as models, etc.?

thanks

Answer 1

Yes, hunk is used for large static distributions, such as textures and geometry, and the zone is for smaller (and possibly mutable) distributions.

Having two (or more!) Zones like this is a common pattern in games. There are two reasons for this:

1) , , . , , // . .

2) / , . - , "", , , :)
