60 // Changes contributed by Bernie Bright <bbright@c031.aone.net.au>
61 // - The new classes in libmisc.tgz define a stream interface into zlib.
62 // I've put these in a new directory, Lib/Misc. Feel free to rename it
63 // to something more appropriate. However you'll have to change the
64 // include directives in all the other files. Additionally you'll have
65 // add the library to Lib/Makefile.am and Simulator/Main/Makefile.am.
67 // The StopWatch class in Lib/Misc requires a HAVE_GETRUSAGE autoconf
68 // test so I've included the required changes in config.tgz.
70 // There are a fair few changes to Simulator/Objects as I've moved
71 // things around. Loading tiles is quicker but thats not where the delay
72 // is. Tile loading takes a few tenths of a second per file on a P200
73 // but it seems to be the post-processing that leads to a noticeable
74 // blip in framerate. I suppose its time to start profiling to see where
77 // I've included a brief description of each archives contents.
82 // C++ stream interface into zlib.
83 // Taken from zlib-1.1.3/contrib/iostream/.
84 // Minor mods for STL compatibility.
85 // There's no copyright associated with these so I assume they're
90 // FlightGear input stream using gz_ifstream. Tries to open the
91 // given filename. If that fails then filename is examined and a
92 // ".gz" suffix is removed or appended and that file is opened.
95 // A simple timer for benchmarking. Not used in production code.
96 // Taken from the Blitz++ project. Covered by GPL.
100 // Some simple string manipulation routines.
102 // Simulator/Airports/
103 // Load airports database using fgstream.
104 // Changed fgAIRPORTS to use set<> instead of map<>.
105 // Added bool fgAIRPORTS::search() as a neater way doing the lookup.
106 // Returns true if found.
109 // Modified fgStarsInit() to load stars database using fgstream.
111 // Simulator/Objects/
112 // Modified fgObjLoad() to use fgstream.
113 // Modified fgMATERIAL_MGR::load_lib() to use fgstream.
114 // Many changes to fgMATERIAL.
115 // Some changes to fgFRAGMENT but I forget what!
