1222 2984d 23h werner / public SVN  
1221 2984d 23h werner /branches/ public SVN  
1220 2984d 23h werner /branches/version1.0/ Version 1.0  
1218 2985d 01h werner / clean up repository - make 1.0 trunk again!  
1217 2985d 01h werner / clean up repository - make 1.0 trunk again!  
1104 3273d 05h werner /branches/iland_regen/ Branch dedicated to playing around with establishment/regeneration.
Goals are:
(i) speed up
(ii) introduction of new features for Yellowstone
 
802 4124d 07h werner /branches/port_qt5_64bit/ merge from trunk up to revision 801  
779 4257d 01h werner /branches/port_qt5_64bit/  
707 4788d 02h werner /trunk/src/ rework of the random numbers in iland.
Now, many (200000) random numbers are precalculated using a given algorithm (there are three or four choices), then the drandom() etc functions read from this array. After some rotations, the numbers are renewed. The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete.
 
706 4788d 19h werner /trunk/src/ some performance tests with random number generators. Results so far are not too indicative.  
705 4788d 22h werner /trunk/src/ series of performance tests / modifications.
Using "valgrind" on the linux virtual machine, some performance
measurements were made.
Some candidates for optimization were tested. (1) the applyLIP()
function (about 30% of total run time in runYear()): here several
inlining options were tested; testing the value of the stamp before
using it (in order to omit the other steps) prooved to be slower than
unsing all stamp values.
(2) the random number generator; here the random number generation is
about 5% of the total run time; the commit contains two/three other
variants.
 
671 4840d 01h werner /trunk/src/ Necessary changes for GPL licence (i.e. headers in all source files)  
639 5000d 23h werner / move current content to the "trunk"  
615 5060d 02h werner /src/ removed windows specific _isnan() calls  
443 5319d 05h werner /src/ problems with multihtreading and the random generator. Crashes revealed that the MersenneTwister class is not multithreadable; The solution now is to have for each Thread in the thread pool one random number generator. This removes the crashes, but makes changes to the code necessary.  
431 5346d 19h werner /src/ included the logLevel-Functions at several locations in the source code.
added a option to only display debug messages in the DebugTimer destructor when elapsed time is longer than one millisecond.
 
349 5441d 03h werner /src/ tested behavior of irandom(from, to). It is clear now, that results are [from, to], i.e. the upper value is also returned. Be careful when using for querying an index for a list/vector.  
289 5566d 15h werner /src/ random - things: added the Picus random-helper-classes (RandomIndex, CustomRandomPDF, ...).
added a 3rd party Mersenne-Twister-Random-Generator (added a 3rdparty) directory.
 
287 5567d 14h werner /src/ Tree initialization (random variant). works almost...  
285 5569d 10h werner /src/core/ loading of the landscape. added "areaMask.imageFile" to "world" in xml file. This loads a image mask that establishes area that are inside and outside the project area respectively.  
216 5588d 16h werner /src/ created a more sophisticated management routine using javascript.  
210 5589d 22h werner /src/ class "Sun", added "site"-varaibles to the project file.  
187 5596d 09h iland /src/ wow. Ressource is correctly spelled as Resource. I jerk.  
186 5596d 14h werner /src/ management 1st version running  
157 5607d 15h werner /src/ cleaning of memory after trees died; this had some impacts on AllTreeIterator and some other places.
added a "Tests" class to combine some simple tests.
 
130 5612d 17h Werner /src/ moved debugDataTable to GlobalSettings...  
117 5618d 14h Werner /src/ new debug macros (which are compiled to NOOP in release mode)  
102 5620d 21h Werner /src/ * added a global XML-node of the project file to GlobalSettings (each setup() routine has access to that)
* loading of stamps for each species.
 
93 5621d 16h Werner /src/ XmlHelper class, the first real test-case for that, some thinking about how to setup the whole system.  
91 5621d 22h Werner /src/ started implementation of SpeciesSet; this includes lots of tinkering around with global functions, Database-connections and that like.  
87 5622d 20h Werner /src/ GlobalSettings Object, reading of global settings meta data, GlobalSettings is a Singleton.  
83 5623d 20h Werner /src/ new structure  
80 5623d 21h Werner / change master structure  
39 5672d 15h Werner /fonstudio/ implementing the application of gridded binary stamps.  
33 5674d 16h Werner /fonstudio/ general handling of stamps. This includes:
* StampContainer class. encapsulates internal storage, fast access, read/write functions to binary streams
* factory-approach for creation of stamps with different size. This can be used to use specific looping routines depending on stamp size.
 
32 5674d 23h Werner /fonstudio/ grid: average() function, more const access operators.
LightRoom: mod. mode of setup (now setup with metric length instead of pixelcount),
fixed "addition of angles" bug.
added generation of "subpixel" stamps.
 
24 5679d 20h Werner /fonstudio/ added global.h (RAD(), GRAD()), some adaptations for hemigrid.
continued implementation of lightroom.
