744 4456d 09h werner /trunk/src/ minor layout-improvement for the about-dialog
started to toy around with the graphics-stack
 
743 4456d 20h werner /trunk/ new version 0.8.2
includes topo modifier for wind module on 10m grid.
 
739 4464d 15h werner /trunk/src/core/ removed some warnings, added a ASSERT to stamp-selection (problem with
old stamps)
 
736 4468d 15h werner /trunk/src/core/ fixed the crashes (I hope).
The problem was either:
(a) if you load just one year of climate and have a leapyear, then the store for climate-days can is too short (it was: years*366, now: years*366 + 1
(b) The value of "mHeightGridTries" (in standloader) was not initialized with disabled "heightGrid".
 
734 4468d 17h werner /trunk/src/ small "fixes" (or tries to fix) as iLand is still crashing...  
733 4470d 12h werner /trunk/src/ trying to find the iland bug??  
732 4501d 14h werner /trunk/src/ initialization of trees with given tree heights. The tree height data (e.g. Lidar data) is loaded from a GIS grid file.
some additional changes with painting different grids.
added also an option to use mapgrids without the 'spatial index' (e.g. for float grids on height grid resolution).
 
707 4586d 15h 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 The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete.
 
705 4587d 10h 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.
 
699 4594d 12h werner /trunk/ standloader now can also initialize from vegetation snapshot databases;
fire-module: fire extinction probability works only after reaching the minimum fire size parameter.
 
697 4595d 10h werner /trunk/ Doxygen documentation revisited.
After re-establishing doxygen documentation (last update: 2009) a lot of smaller/medium documentation fixes.
Documentation is something that could definitely be always improved ;)
 
671 4638d 14h werner /trunk/src/ Necessary changes for GPL licence (i.e. headers in all source files)  
639 4799d 11h werner / move current content to the "trunk"  
603 4868d 18h werner /src/ added the target "Map" to functions of the StandLoader; also changed some functions in scriptglobal.cpp (addTreesOnMap).
Interesting: you can easily pass (scripted) object to slots as Pointer - but not so easy as references (for refs you would need to qScriptRegisterMetaType()) - it took me a while find this out...
 
600 4869d 08h werner /src/ corrected grid export (flipping of y-axis)
added initialization of saplings; StandLoader contains now a routine similar to the one for larger trees to distribute saplings; additionally, a script function (Globals.addSaplingsOnStand()) can be used to use this functionality.
 
550 4919d 16h werner /src/ some fixes with landscape initialization, made some debug messages conditional on various places.  
549 4919d 17h werner /src/ initialization based on stand grids.
added new functionality for that in StandLoader plus minor changes in Model or MapGrid.
 
445 5115d 19h werner /src/core/ added database species parameters for seed dispersal, fixed a bug with random generator in StandLoader, change maturity criterion for seed production to age instead of height.  
444 5117d 15h werner /src/core/ added a "randomGenerator" - function to the resource unit -> this should be used when fetching random numbers from within functions that are executed in a multi-threaded way. You could also use GlobalSettings::instance()->randomGenerator().  
431 5145d 07h 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.
 
393 5173d 18h werner /src/ fixed a bug in StampContainer when loading trees with invalid hd-ratio (too low trees).
fixed a bug that caused a crash when seed dispersal was disabled.
added return values for stand init routines (also those that accessed by scripting) and cleaned up the documentation.
 
389 5176d 06h werner /src/ fixed small glitches with single tree initialization (species name at last position); changes to management routines.  
388 5176d 08h werner /src/core/ remodified the age calculation. Now the age is estimated based on the current height relative to h_max. The aging-calculation itself is no longer changed by that.  
384 5176d 17h werner /src/core/ various changes in load of initialization  
381 5176d 19h werner /src/core/ appropriate handling of tree age during initialization.
if no age is provided in the input file only the tree height is used for the aging calculation. The tree "age" in that case reflects only the number of years since initialization.
 
319 5323d 18h werner /src/ loading of the environment  
312 5330d 16h werner /src/core/ increased freq. of sorting for low stem numbers  
311 5330d 17h werner /src/core/ improve loading of tree distributions (density per line)  
299 5343d 18h werner /src/ fixed bug with disabled debug outputs
added modified LRI to NPP-debug output
new species parameter "probStressYears".
documentation (wiki-links)
 
294 5363d 23h werner /src/ lots of scripting stuff: new global functions (include, alert)
new methods of the "Globals" javascript object (set, setting, addTrees, ...)
 
290 5364d 07h werner /src/ using now the CustomRandomPDF class (from Picus) for the custom probabilty density function used in the standloader.  
289 5365d 03h werner /src/ random - things: added the Picus random-helper-classes (RandomIndex, CustomRandomPDF, ...).
added a 3rd party Mersenne-Twister-Random-Generator (added a 3rdparty) directory.
 
288 5366d 01h werner /src/ more stand loading  
287 5366d 02h werner /src/ Tree initialization (random variant). works almost...  
285 5367d 22h 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.  
284 5368d 01h werner /src/ loading of different ini-files on the worlds landscape.  
281 5368d 02h werner /src/ setup of the world - remodeled the init-routine in Model, changed the init of stands (also some xml-keys). added a storage for variables local to rseource units (e.g. nitrogenAvailable).  
270 5372d 00h werner /src/core/ added warning if species table not found  
247 5378d 03h werner /src/ global script object (ScriptGlobal).
Doxygen documentation refinements.
