[guide-user] DSS 'fixed', again

Bill J. Gray Nov 22, 1999

Hmmmm... It sounds very much as if, this time, I got everything
to 'work' except that GZIP386 is falling down on NT boxes.

I checked with the GZip Web site (http://www.gzip.org) and found
that, in addition to the DOS GZip I distributed, there is now a
separate executable for Win95, 98, and NT machines. I've tried it
out, and it seems to work just fine.

So there is now yet another REALSKY.ZIP on my Web site. It contains
the same GET_DSS.EXE as before, but with the new GZip code. (For
some reason, the new GZip is smaller than the 'original' one, so
REALSKY.ZIP is down to about 65 KBytes.)

past, I'd expected to do a full-fledged 'line-intersecting-an-ellipsoid'
for each pixel. Instead, I figured out a way to slightly modify the
existing routine... it adds just a few operations per pixel.
