good evening, Indeed, in 2008, several (C)DT implementations (including famous "Triangle" implementation) have been coupled with OrbisGIS so as to compare performances. It seems the one of Michaël (thanks to him for his useful help) was the fastest one. I've also tried to "enhance" his own implementation adding a sweepline and a (not fully debug yet - job was postponed) soft breakline insertion method. All those dev will be published asap. -- Thomas LEDUC
