Hi, We have tested : - TRIANGLE with a wrapper for JTS, - WATERBUGS, - Paul job's, - VISAD delaunay triangulation, - GTS. but nothing correspond to our aims. We have started the implementation of sweep-line algorithm available here : http://www.cescg.org/CESCG-2004/web/Domiter-Vid/. The API w

Geoff, I don't think we made the official jump to Java 1.6 just yet. (This doesn't mean one of us didn't accidentally introduce a dependency on 1.6 into the nightly build.) Stefan can probably confirm this for us. I wouldn't mind a discussion of when we can make the jump to 1.6. I would like to

Dear OpenJumper, We are working at IRSTV on a CDT api in JAVA. The api will integrate some functionalities like insert polygon with hole, node, line and skeleton refinement. It's a transposition of my thesis work in pure java. Feel free to send me a mail. R1. 2008/4/16, Geoffrey G Roy <[EMAIL

Hei Christopher thanks for your outline :) I actually have not that much background knowledge to evaluate if what you do propose is good, but I guess you know it better. But modularity is always a plus and documentation is sufficient. However.. a good rule is to always start with a simple model
