Branch dedicated to playing around with establishment/regeneration.
Goals are:
(i) speed up
(ii) introduction of new features for Yellowstone |

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. |

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 ;) |

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. |

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 |

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. |

* removed compiler warnings |

- drawing GUI in MainWindow
- "Opacity" of tree crowns as a function of leafarea (and crown area;
crown radius is stored in LIP-stamp). |

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! |

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) |

now to each "writer" stamp a reader stamp (i.e. the "crownradius") is directly attached. Therefore some changes in tree and treespecies. |

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. |

LightRoom: use sum instead of average

Handling of stamps (read, write, ...) |

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. |

grid: average() function, more const access operators.
LightRoom: mod. mode of setup (now setup with metric length instead of pixelcount),
fixed "addition of angles" bug.
added generation of "subpixel" stamps. |

change "stamp" to "imagestamp", added a new "stamp" which should be more like the real, efficient stamp used in iLand.
started impl. of lightroom - batch modus. |
