The14theditionoftheInternationalConferenceonDiscreteGeometryforC- puterImagerywasheldinLyon, France, April16-18,2008.DGCI2008attracted many researchers from all around the world. Indeed, 76 papers were submitted, from 24 di?erent countries (13 European and 11 non European), con?rming the international status of the conference. Once reviewed, 45 papers were accepted for publication in the present LNCS volume. In all, 23 papers were scheduled for oral presentation in single-track sessions, and 22 papers were presented as posters, with preliminary plenary sessions with very short presentations of these posters. Three invited speakers gave lectures on topics ranging from connected ?elds to the theoreticalfoundations of discrete geometry: Dinesh Manocha (U- versityofNorthCarolinaatChapelHill, USA), UllrichKo ]the(UniversityofH- delberg, Germany) and Jean-Pierre Reveilles (University of Auvergne, France). Building on the experience of the previous editions, this edition was the - casion to remodel the paper selection process in order to improve the overall quality of the conference. These changes were based on an update and red- nition of the topics covered by the conference, in such a way that most of the present-day works in discrete geometry naturally 't in one topic. The members ofthe ProgramCommittee werethen chosenfor their expertisein these di?erent topics.Theysupervisedthereviewingprocessofthepapersrelatedtotheirtop
