I'm looking for a library for java containing tools for mesh operations (data structures, mesh simplifying algorithms, triangulations). Somenthing like http://gts.sourceforge.net/index.html but for Java.
There was a similar question on Stack, but it was from '09 and there was no satisfying answer... so once again.
You can have a look at the cgal-bindings project which contains SWIG bindings of the CGAL library. It is working fine with Java. For example, you'll have access to the Delaunay triangulation in 2D and 3D.
