74 5528d 00h Werner /fonstudio/ Changed algorithm for dominant height grid.
* "smooth" height values if trees are not in center of 10m height Grid
* the height-value is the maximum value of all the trees in the pixel (thus no part of the crown is above this height)		  
70 5533d 02h Werner /fonstudio/ MainWindow: the "scale to a height" FON-visualization.
Tree: change behavior of reading: now the value of the height grid is considered for every pixel (see also bugfix20090812.xls).		  
62 5561d 02h Werner /fonstudio/ * Tree:heightGrid(): changed calculation scheme for dominant height
* LightRoom: mod of aggregation: now weighing with the local dominant height (consistently with the usage in the FON-studio).		  
61 5561d 03h Werner /fonstudio/ * modified bin-sizes in StampContainer
* cleaned Tree-class (dropped some old code and refs from other places)		  
60 5561d 05h Werner /fonstudio/ application of stamps now considers local height of Z* (see also prev. commit)
in Tree::applyStamp()		  
59 5561d 05h Werner /fonstudio/ changed way of height-grid-calculation: (Tree::heightGrid()):
a tree affects the height grid of more cells (up to the 45° angle).		  
58 5562d 01h 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)		  
53 5563d 01h Werner /fonstudio/ additive mode, relate impact sum to Z*-crown height.  
52 5563d 02h Werner /fonstudio/ modified to additive again;
* in Lightroom again the average up to the treeheight is summed up
* while extracting stamps, an upper limit of 47x47px (i.e. with 2m grid size approx. 1ha) is used. Now the criterion is based upon absolute values - maybe switch to relative values again (to avoid huge stamps)??		  
51 5563d 05h Werner /fonstudio/ changed application/stamp production to a multiplicative approach, disengaged the height field.  
48 5566d 01h Werner /fonstudio/ grid: bugfix
mainwindow: added different visualizations
tree: adopted to new scheme: dominance height split in "above Z*" and "below Z*"		  
47 5566d 02h Werner /fonstudio/ now to each "writer" stamp a reader stamp (i.e. the "crownradius") is directly attached. Therefore some changes in tree and treespecies.  
45 5566d 04h Werner /fonstudio/ apply stamps at domiance grid  
42 5566d 05h Werner /fonstudio/ additionally storing crown radius in stamp file.
readout of stamps using radius-stamps.		  
40 5566d 23h Werner /fonstudio/ reading out of stamp values.
lots of additional small changes.		  
39 5568d 00h Werner /fonstudio/ implementing the application of gridded binary stamps.  
38 5568d 00h 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.		  
32 5570d 07h Werner /fonstudio/ 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.		  
30 5573d 05h Werner /fonstudio/ 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.		  
16 5576d 05h Werner /fonstudio/
