We are honored and pleased to present the proceedings of the 1st Ibero-American Symposium in Computer Graphics (SIACG 2002), held in Guimarães.
This conference was very special since it marked the first actual attempt to join the Computer Graphics communities in both the Iberian Peninsula and Latin America. It is expected that a series of similar events can follow this symposium in the next years and alternating the local between Europe and South America.
SIACG 2002 has provided a valuable forum for the discussion on technology and scientific aspects related to Computer Graphics. We hope that it will promote cooperation through joint projects in the near future as well as the interchange of people from different countries.
All papers were submitted electronically and reviewed for their contents by qualified and independent reviewers. The International Programme Committee selected a total of 36 full papers out of 61 contributions. They have been written in English, although presentations could be delivered in Portuguese, Spanish or English. In addition to research papers, nearly one third of the accepted submissions can be classified as practice and experience papers.
A different way to measure the impact of the symposium is by observing that the papers included in these proceedings were prepared by authors from 10 different countries.
Additionally, in a companion publication to the proceedings one can find a set of refereed short papers. This written material has provided the opportunity for most participants to present new ideas and promising work in progress yet at a more or less embryonic stage.
Many people deserve credit for helping in the genesis of the symposium and their work must be referred in the conference proceedings. We would like to express our sincere thanks to all members of the International Programme Committee and to the invited reviewers for their great effort to get all the papers reviewed in time.
We also thank the invited speakers Markus Gross, Eugene Fiume and Gabriel Taubin, and express our gratitude to the Organizing Committee for the work done in organizing this conference in Guimarães.
However, since the quality of any conference cannot be dissociated from the quality of the corresponding submissions, our best thanks go to the authors who contributed with their valuable papers and made this conference an undeniable success.
