Hi Gerd,
we have ever 2 problems: how to calculate the next value and how we have
to encoding this value.
#1: If we have not a plateau, then we have a "Standardwert". For the
calculation of a "Standardwert" we have to 3 differend cases depend on the
value hdiff(n, m-1) = h(n, m) - h(n-1, m) (horizontal difference, see at
the end of "Datenberechnung"). max is highest possible value in this
64x64-subtile.
#2: We have to decide, is it "Längencodierung", "Hybride Codierung" or if
they are not possible, "Binärcodierung für große Zahlen". But we have no
choice, we have to use that kind, that the algorithms say (see "
Umschaltung der Codierart"). That do in TileEncoder.cs the class
CodingType and the derived classes.
I'm sorry, but TileEncoder.cs is not written for speed or good
understanding. It is only for exploring DEM and, in Input2, for showing,
what's going on. There is much place for optimizing. ;)
