If you are on Windows, you will need to first figure out how to compile
qhull for Windows. We haven't done so yet.
If you are on unix, follow the octave-forge/main/geometry/readme
instructions
for installing qhull. I haven't tried yet with the most recent qhull
release.
Download the correct version of octave-forge (octave.sf.net) for your
particular
version of octave (the latest is for octave 2.1.40 I believe --- if you
are using
something more recent, you will need to get the CVS version).
./configure
make
make install
griddata does not work as quickly as I would like. Talk to the
qhull author about how to improve it if it is not fast enough for
you.

However, I have found a function called griddata, which seems to do what I
want, but it in turn uses the function delaunayn, which I do not have. I have
managed to find a cc file on the repoitory, bit I do not know how to compile
it.
