744 4454d 05h werner /trunk/src/ minor layout-improvement for the about-dialog
started to toy around with the graphics-stack
 
743 4454d 16h werner /trunk/ new version 0.8.2
includes topo modifier for wind module on 10m grid.
 
739 4462d 12h werner /trunk/src/core/ removed some warnings, added a ASSERT to stamp-selection (problem with
old stamps)
 
736 4466d 12h 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 4466d 14h werner /trunk/src/ small "fixes" (or tries to fix) as iLand is still crashing...  
733 4468d 09h werner /trunk/src/ trying to find the iland bug??  
732 4499d 11h 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 4584d 11h 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 The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete.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 4585d 07h 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 4592d 09h 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 4593d 07h 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 4636d 10h werner /trunk/src/ Necessary changes for GPL licence (i.e. headers in all source files)  
639 4797d 08h werner / move current content to the "trunk"  
603 4866d 15h 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 4867d 04h 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 4917d 13h werner /src/ some fixes with landscape initialization, made some debug messages conditional on various places.  
549 4917d 14h werner /src/ initialization based on stand grids.
added new functionality for that in StandLoader plus minor changes in Model or MapGrid.
 
445 5113d 16h 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 5115d 12h 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 5143d 04h 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.
