Here's a few changes I made to fg-0.58 this weekend. Included are the
following features:
- Sun and moon have a halo
- The moon has a light vector, moon_angle, etc. etc. so that we can have
some moonlight during the night.
- Lot's of small changes tweakes, including some stuff Norman Vine sent
me earlier.
- The new classes in libmisc.tgz define a stream interface into zlib.
I've put these in a new directory, Lib/Misc. Feel free to rename it
to something more appropriate. However you'll have to change the
include directives in all the other files. Additionally you'll have
add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
test so I've included the required changes in config.tgz.
There are a fair few changes to Simulator/Objects as I've moved
things around. Loading tiles is quicker but thats not where the delay
is. Tile loading takes a few tenths of a second per file on a P200
but it seems to be the post-processing that leads to a noticeable
blip in framerate. I suppose its time to start profiling to see where
the delays are.
I've included a brief description of each archives contents.
Lib/Misc/
zfstream.cxx
zfstream.hxx
C++ stream interface into zlib.
Taken from zlib-1.1.3/contrib/iostream/.
Minor mods for STL compatibility.
There's no copyright associated with these so I assume they're
covered by zlib's.
fgstream.cxx
fgstream.hxx
FlightGear input stream using gz_ifstream. Tries to open the
given filename. If that fails then filename is examined and a
".gz" suffix is removed or appended and that file is opened.
stopwatch.hxx
A simple timer for benchmarking. Not used in production code.
Taken from the Blitz++ project. Covered by GPL.
strutils.cxx
strutils.hxx
Some simple string manipulation routines.
Simulator/Airports/
Load airports database using fgstream.
Changed fgAIRPORTS to use set<> instead of map<>.
Added bool fgAIRPORTS::search() as a neater way doing the lookup.
Returns true if found.
Simulator/Astro/
Modified fgStarsInit() to load stars database using fgstream.
Simulator/Objects/
Modified fgObjLoad() to use fgstream.
Modified fgMATERIAL_MGR::load_lib() to use fgstream.
Many changes to fgMATERIAL.
Some changes to fgFRAGMENT but I forget what!
