Re: [Databionic-ESOM-User] 3D Visualization

[<fa...@in...>]

http://www.mathematik.uni-marburg.de/~databionics/en//images/stx_umx.jpg

was created using a java3d tool that is not available anymore. just
recently someone contacted me with the interest of developing 3d support
for the esom tools, but I don't know if and when it will be available.

the picture in

http://www.mathematik.uni-marburg.de/~databionics/en//downloads/papers/ultsch05clustering.pdf

was created using matlab. the esom tools already include matlab code to
load the files generated by the java tools, I will add the code used for
3D plotting to the next version.

it should be pretty easy to import the output of the esom tools (*.umx
for the heights and *.bm for the best matches) into other 3d tools. the
file formats are documented in the manual. please let me know if you
need further assitance and report any success.

personally, I like to work with 2D better. it's easier to manually
select data and create classes. 3D looks better of course, but it does
not necessarily aid the analysis.
