[Freeciv-Dev] (PR#3936) introducing native coordinates

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

[jdorje - Sat Apr  5 03:48:14 2003]:

> Native coordinates (sometimes called "compressed" coordinates in the
> past) are a concept Ross came up with to make isometric (and other
> non-standard) maps easier to deal with.  They save around 50% memory
> (and on disk, in savegames) for map storage over "standard" map
> coordinates and make topology operations *much* simpler.  Other
> coordinate systems may share one of these properties, but none have
> both.  In the process, they invalidate the need for "regular" map
positions.
> 
> The patch introduces native_to_map_pos and map_to_native_pos macros into
> map.h, along with one very simple user.  I've also written an
> explanation of the coordinate systems for doc/HACKING.  I'd like
> feedback on this explanation, particularly from people who don't already
> know what "native coordinates" are.

Discussion on this design died a while ago.  And what's worse, most of
it's not associated with the RT ticket for some reason.  Raimar, what
was your final position on this?
