- 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!
I've created some new classes to enable pointers-to-functions and
pointers-to-class-methods to be treated like objects. These objects
can be registered with fgEVENT_MGR.
File "Include/fg_callback.hxx" contains the callback class defns.
Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
some minor tweaks to STL usage.
Added file "Include/fg_stl_config.h" to deal with STL portability
issues. I've added an initial config for egcs (and probably gcc-2.8.x).
I don't have access to Visual C++ so I've left that for someone else.
This file is influenced by the stl_config.h file delivered with egcs.
Added "Include/auto_ptr.hxx" which contains an implementation of the
STL auto_ptr class which is not provided in all STL implementations
and is needed to use the callback classes.
Deleted fgLightUpdate() which was just a wrapper to call
fgLIGHT::Update().
Modified fg_init.cxx to register two method callbacks in place of the
old wrapper functions.
- use strings for fg_root and airport_id and added methods to return
them as strings,
- inlined all access methods,
- made the parsing functions private methods,
- deleted some unused functions.
- propogated some of these changes out a bit further.
Eliminated libtool use.
Added options to specify initial position and orientation.
Changed default fov to 55 degrees.
Added command line option to start in paused or unpaused state.
