Hi again,
  I asked Bruno Levy about your references. He told me:

.Marc Alexa http://www.cg.tu-berlin.de/menue/publications/
.Olga Sorkine http://cs.nyu.edu/~sorkine/publications.html
.Igarashi http://www-ui.is.s.u-tokyo.ac.jp/~takeo/
.Cindy Grimm http://www1.cse.wustl.edu/~cmg/research.php
.Mesh Mixer http://www.meshmixer.com/

  Keep up with the good work !

Hi :)

 Oh yes :) ! I´m aiming at SIGGRAPH 2011 , perhaps is too high goal for me
but I think I´m ready to take the chance :)

 The good thing about the algorithm I´m developing is that it is
relatively independent from the subdivision scheme used, so the simpler,
the faster to calculate and for several architectural decitions I´m
enforcing triangles only. (you will understand why sculptris use
triangles only too ;) ) so I end up using Loop subdivision scheme.

 Definately Centriodal Voronoi Tessellations are an appealing
remeshing/relaxation algorithm and I have being tempted to put my hands
on it, but I don´t know the status of the quad remeshing GSOC and I don´t
want to overlap with that cool project, perhaps in the future, when
Unlimited Clay is fleshed out I could extend its relaxation scheme to
include it, it will be fun ;)

 Thanks for your advices ... I wish you the best of luck too.
