671	4628d 16h	werner	/trunk/src/	Necessary changes for GPL licence (i.e. headers in all source files)
639	4789d 14h	werner	/	move current content to the "trunk"
487	4999d 11h	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	5145d 10h	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	5145d 18h	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	5313d 19h	werner	/src/	* check for NaN in readLIF_torus() (Tree). * dump() function in Stamp * removed compiler warnings
149	5398d 04h	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	5398d 10h	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	5401d 04h	Werner	/src/	added a 64x64 stamp while reinvoking the FonStudio
83	5412d 11h	Werner	/src/	new structure
80	5412d 12h	Werner	/	change master structure
58	5455d 08h	Werner	/fonstudio/	working version of light alogorithnm: * steps during read: own_xy = 1 - writer_xy * la_factor / h_dom value_xy = grid_xy / own_xy lightvalue = sum( value_xy * reader_xy) [ sum(reader) = 1 ] additional correction for overstorey: if h > h_dom: lightvalue = 1 - (1 - lightvalue) * h/h_dom other issues: * added buffer around sim. area * cleaned xml-file and code to interpret * fixed Viewport (handling of negative coordinates - see buffer) * fixed StampContainer, added finalizeSetup() - (filling up of the lookup map)
47	5459d 08h	Werner	/fonstudio/	now to each "writer" stamp a reader stamp (i.e. the "crownradius") is directly attached. Therefore some changes in tree and treespecies.
43	5459d 11h	Werner	/fonstudio/	changed lightroom again to aggregate averages of shadowing along the full height (including crown). additionally saved the value at the center which will be used for the "dominance" height of the tree. modified file structure of binary stamp files to include dominance values.
42	5459d 12h	Werner	/fonstudio/	additionally storing crown radius in stamp file. readout of stamps using radius-stamps.
40	5460d 06h	Werner	/fonstudio/	reading out of stamp values. lots of additional small changes.
38	5461d 07h	Werner	/fonstudio/	LightRoom: use sum instead of average Use of Lightroom in mainwindow: cut parts of lightroom result based on values and save as binary stamp file. create class TreeSpecies, start to impl. use of stamps in Tree.
35	5463d 04h	Werner	/fonstudio/	various fixes (still trying to load/save stamps).
34	5463d 06h	Werner	/fonstudio/	Handling of stamps (read, write, ...)
33	5463d 07h	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.
