Yep, a set of structures like that would get utterly huge if you had
even a moderately sized world. Things like oct-trees, quad-trees,
R-trees, etc. can be used to compress things like that down, but the
compression is really only effective if there are comparatively few
regions of detail. These things are typically used to compress
bitmaps and geographical information, so they'd certainly be
applicable. One could get away with using a set of adjacent n-sided
polygonal regions to compose the world (something I will probably end
up doing since I plan to have a very large world--probably in
conjunction with oct-trees, though exactly how is still up in the
air).
I wonder at using some sort of RLE, since if you compressed the entire
array, wouldn't you have to uncompress the first n elements in order to
address some element deep into the array?
