Interesting comparison, Michael. Is your code online somewhere? What
algorithm does it use, and what data structure for the triangulation?
In the JTS API you don't have to create the triangles as a MultiPolygon
- that's just provided as a simple option for viewing them in the JTS
TestBuilder.
One other thing the JTS API supports computing a Conformal Delaunay
Triangulation as well. This is done using the Incremental Insertion
algorithm to refine the triangulation. So this is a bit of a constraint
on the design and implementation. I'm not sure if CDTs are supported by
other D
Michael,
I should have looked before I wrote - I just found the link you sent a
while ago to your code (for others benefit -
http://geo.michaelm.free.fr/OpenJUMP/resources/ ).
So you are using Incremental insertion, with a Triangle- based data
structure. It looks like your code handles Constr
It is a great idea landon. I can work on translating the menus. I will put this
as my 1st one on the Openjump list.

Right, I see the sorting step now. Out of curiosity, did you check to
see if it was any faster using an array and Collections.sort, rather
than a TreeSet? I would have thought building a tree was slower than
doing a single sort of an array, followed by removing duplicates by
traversing the ar
Yep, Michael summarizes it very well.
I'm also a hesitating to add a big lib of which we may use only a few
things. Although deegree may offer a lot of functionality for the future
(GML and CRS wise and the extended feature model?).
Does it actually make a difference in terms of memory footprint
Hei all,
thanks to Stephan Holl and Sascha Teichmann the Intevation GmbH*
(Germany) has setup a nightly build process for OJ and copies the NB
over to the usual directory:
http://jump-pilot.sourceforge.net/download/nightlybuild/
the structure is a little bit different, but the file
openjump-c
Thank you Stefan, Stephan, and Sascha !

wow.. those geeky talks ;)
I would like to know much more about Comp Geom.

Hei all,
just some info:
we have now one month after the OJ 1.3 windows setup release reached 997
downloads. The platform independent zip file (offered about 1 week
earlier) has 1119 downloads by now.
not bad, eyhh :)
keep up the good work Larry, Andreas, Jukka, Peppe, Martin, Landon ... -

Hi,
I have always recommended people to download from the nightly builds.
Now when they are at Sourceforge could it be possible to get statistics
of those downloads as well?
