Thanks for reminding me - I had completely forgotten.

IIRC, sources are at

DDJ can be found at :

and, again from memory, they have the source available, too, but
not the article. There are other BSP related articles from 1995,
including one by Mike Abrash (, and May/June, again
from memory).

I will have to add the pointers to the Quake Developers pages.
However, the article itself is copyrighted, and not one of those
available at the DDJ site. If somebody does have a copy, perhaps
we could get a summary of some kind. There is a README in the
source archive.
