124 // Changes contributed by Bernie Bright <bbright@c031.aone.net.au>
125 // - The new classes in libmisc.tgz define a stream interface into zlib.
126 // I've put these in a new directory, Lib/Misc. Feel free to rename it
127 // to something more appropriate. However you'll have to change the
128 // include directives in all the other files. Additionally you'll have
129 // add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
131 // The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
132 // test so I've included the required changes in config.tgz.
134 // There are a fair few changes to Simulator/Objects as I've moved
135 // things around. Loading tiles is quicker but thats not where the delay
136 // is. Tile loading takes a few tenths of a second per file on a P200
137 // but it seems to be the post-processing that leads to a noticeable
138 // blip in framerate. I suppose its time to start profiling to see where
141 // I've included a brief description of each archives contents.
146 // C++ stream interface into zlib.
147 // Taken from zlib-1.1.3/contrib/iostream/.
148 // Minor mods for STL compatibility.
149 // There's no copyright associated with these so I assume they're
150 // covered by zlib's.
154 // FlightGear input stream using gz_ifstream. Tries to open the
155 // given filename. If that fails then filename is examined and a
156 // ".gz" suffix is removed or appended and that file is opened.
159 // A simple timer for benchmarking. Not used in production code.
160 // Taken from the Blitz++ project. Covered by GPL.
164 // Some simple string manipulation routines.
166 // Simulator/Airports/
167 // Load airports database using fgstream.
168 // Changed fgAIRPORTS to use set<> instead of map<>.
169 // Added bool fgAIRPORTS::search() as a neater way doing the lookup.
170 // Returns true if found.
173 // Modified fgStarsInit() to load stars database using fgstream.
175 // Simulator/Objects/
176 // Modified fgObjLoad() to use fgstream.
177 // Modified fgMATERIAL_MGR::load_lib() to use fgstream.
178 // Many changes to fgMATERIAL.
179 // Some changes to fgFRAGMENT but I forget what!
181 // Revision 1.3 1998/08/27 17:01:55 curt
182 // Contributions from Bernie Bright <bbright@c031.aone.net.au>
183 // - use strings for fg_root and airport_id and added methods to return
185 // - inlined all access methods,
186 // - made the parsing functions private methods,
187 // - deleted some unused functions.
188 // - propogated some of these changes out a bit further.
190 // Revision 1.2 1998/08/25 20:53:24 curt
191 // Shuffled $FG_ROOT file layout.
193 // Revision 1.1 1998/08/25 17:19:13 curt

205 // STL includes don't use .h
206 // Small view optimizations.
208 // Revision 1.5 1998/05/29 20:37:22 curt
209 // Tweaked material properties & lighting a bit in GLUTmain.cxx.

220 // Revision 1.2 1998/04/28 21:42:50 curt
221 // Wrapped zlib calls up so we can conditionally comment out zlib support.
223 // Revision 1.1 1998/04/25 15:11:11 curt
224 // Added an command line option to set starting position based on airport ID.
