The old delaunay code (from the GMT project ) had an error and wasn't
usefull for other geometric operations. (voronoi diagramms, convex
Thats why, I looked for a library which has to be:
* GPL compatible
* cover at least delaunay triangulation, voronoi diagramms and fast
* relatively small
* written in C or C++
I think the qhull package  fits thats needs.
For the 'lawyers': could you check the license, is it indeed GPL
I have made a slimmed qhull package  which includes only the files
needed to build the library and an adapted makefile. If you want to look
at examples or the
documentation, please take the original package .
The first function which uses the qhull lib is delaunay. You can get a
tarball from my homepage .
My question to you (especially jwe): What do you think is the best way
to go on?
* Keep the qhull lib and the DLD functions separate from octave
* include the DLD-functions in octave and
check at the configure stage for a user installed libqhull.
* include both in octave
P.S the qhull homepage seems to be unavailable today.
