I've developed a system for storing a cubic world 64K on each side. It's
basically a binary tree in 3D, thereby compressing the unused areas into
only a few bytes. It works fine, is fast and probably about as efficient a
way of storing this much data as there is.
Having a map this big isn't the problem- populating/defining it is. And on
top of that you have to have a game that allows players to travel vast
distances quickly- otherwise 90% of your billion or so rooms will never be
For populating the map I use a bit mapped image (e.g. GIF) to map converter.
This unfortunately is quite slow, but it seems to work fine. (It's slow
because I use IPC to ask the running mud server to make the changes. I'm
sure I could dramatically speed it up by just writing the GIF into the raw
map file.) One major advantage of this is that you can digitise a real map
of you favourite continent/island/town.
As a secondary form of population I have used maze generations, obviously
this only has use in the labyrinth sections of the map. Though with a little
imagination and tweaking of the maze algorithm, it can be expanded to, say,
defining the path of a river (+tributaries) through a forest.
If anyone has any other ways of defining large areas of maps I'm interested
to hear them.
Once this information is in I use code based on that developed by Richard
Woolcock and myself for the Dark/Last City mud (I believe the original idea
was his) to create dynamic descriptions of each room. With some careful text
processing and a lot of imagination Rich has been able to generate some very
As far as moving around a large map is concerned- I'm waiting for Rich to
solve the problem, then I'll pinch his ideas :)
