O(n^2 log(n)) ]
Release 0.1: source |
Out of my thesis work at the University of Applied Sciences Northwestern
Switzerland evolved a library for mesh and NURBS processing in Java.
The library is open source and
can be found here:
jgeom. The library is not
actively developed anymore and was removed from dev.java.net. The project has migrated to sourceforge and the latest
version is available here: jgeom. Part of the library
was is incorporated into XJ3D and in toxiclib,
which appears to be actively developed.
