1222 2725d 15h werner / public SVN  
1221 2725d 15h werner /branches/ public SVN  
1220 2725d 15h werner /branches/version1.0/ Version 1.0  
1218 2725d 17h werner / clean up repository - make 1.0 trunk again!  
1217 2725d 17h werner / clean up repository - make 1.0 trunk again!  
1104 3013d 22h werner /branches/iland_regen/ Branch dedicated to playing around with establishment/regeneration.
Goals are:
(i) speed up
(ii) introduction of new features for Yellowstone		  
779 3997d 17h werner /branches/port_qt5_64bit/  
739 4406d 19h werner /trunk/src/core/ removed some warnings, added a ASSERT to stamp-selection (problem with
old stamps)		  
705 4529d 14h 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.		  
697 4537d 14h 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 4580d 18h werner /trunk/src/ Necessary changes for GPL licence (i.e. headers in all source files)  
639 4741d 15h werner / move current content to the "trunk"  
487 4951d 12h werner /src/core/ some performance optimizations done on Linux with valgrind /
KCacheGrind.
stamp: did inlining of "distanceToCenter" (is still relatively expensive
due to heavy usage in e.g. applyLip)
Saplings: removed the very exensive way to check if a sapling of a
species is already on a given pixel; we now use a std::bitmap for that
purpose.
grid: optimized the "indexOf(float*)"-method; this method is used very
often.		  
401 5097d 12h werner / starting from a change in the LIP-pattern and the LIP-application a grand tour through followed.
StampContainer has now a static grid that holds distances to the stamp-center. This is used by the tree when applying a stamp.cpp
minor changes necessary due to the switch to Qt 4.6		  
400 5097d 19h werner /src/ changed the binary format of the LIP stamps (included a magic number, a version and a call to setVersion()). Changed the way of aggregating the "shadow" in the lightroom: now (again) the result value represents the mean "shadow" per meter below the 45° line.  
321 5265d 20h werner /src/ * check for NaN in readLIF_torus() (Tree).
* dump() function in Stamp
* removed compiler warnings		  
149 5350d 06h werner /src/ - drawing GUI in MainWindow
- "Opacity" of tree crowns as a function of leafarea (and crown area;
crown radius is stored in LIP-stamp).		  
145 5350d 12h Werner /src/ Run and compiled iLand on Linux (Kubuntu) with a virtual machine. The gcc on Linux issues lots of warnings which I fixed on the Linux side. Also fixed TTickTack (the clock issue).
Now iLand also runs on Linux - nice!		  
131 5353d 05h Werner /src/ added a 64x64 stamp while reinvoking the FonStudio  
83 5364d 13h Werner /src/ new structure
