removed some warnings, added a ASSERT to stamp-selection (problem with
old stamps) |

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". |

small "fixes" (or tries to fix) as iLand is still crashing... |

trying to find the iland bug?? |

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). |

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 The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete. |

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. |

standloader now can also initialize from vegetation snapshot databases;
fire-module: fire extinction probability works only after reaching the minimum fire size parameter. |

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 ;) |

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... |

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. |

initialization based on stand grids.
added new functionality for that in StandLoader plus minor changes in Model or MapGrid. |

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. |

/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(). |

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. |

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. |
