Initial stab at a threaded tile loader contributed by Bernie Bright. He writes: Here are the final changes to add threads to the tile loading. All the thread related code is in the new FGTileLoader class. ./configure.in ./acconfig.h Added --with-threads option and corresponding ENABLE_THREADS definition. The default is no threads. ./src/Scenery/tilemgr Removed load_queue and associated references. This has been replaced by a new class FGTileLoader in FGNewCache. Made the global variable global_tile_cache a member. schedule_needed(): removed global_tile_cache.exists() tests since sched_tile() effectively repeats the test. initialize_queue(): removed code that loads tiles since this is now performed by FGTileLoader. update(): ditto ./src/Scenery/newcache Added new class FGTileLoader to manage tile queuing and loading. tile_map typedefs are private. exists() is a const member function. fill_in(): deleted load_tile(): added. ./src/Scenery/FGTileLoader The new threaded tile loader. Maintains a queue of tiles waiting to be loaded and an array of one or more threads to load the tiles. Currently only a single thread is created. The queue is guarded by a mutex to synchronize access. A condition variable signals the thread when the queue is non-empty. CLO: I made a few tweaks to address a couple issues, hopefully what we have is solid, but now we kick it out to the general public to see. :-) 2001-04-11 02:47:15 +00:00			`FGTileLoader.cxx FGTileLoader.hxx \`
Updates, optimizations, and restructures from Norman Vine. 2000-06-15 22:32:26 +00:00			`hitlist.cxx hitlist.hxx \`
Rewrote the tile scheme to use a "map" structure rather than "vector" structure. The new approach is simpler, more flexible, and more dynamics. We can now dynamically size the tile cache up and down. Also, the range of tiles to load is now dependent on visibility and is calculated to always bring in enough tiles. 2000-12-03 20:15:46 +00:00			`newcache.cxx newcache.hxx \`

Started work on a dynamic tile cache. Did a bit of renaming and reorganizing. 1999-06-12 21:12:13 +00:00			`tileentry.cxx tileentry.hxx \`
