Preface The Visual Computer (Vol 38 issues 09–10)

Welcome to the special issue of the 39th Computer Graphics International conference (CGI 2022). CGI is one of the oldest international conferences in Computer Graphics in the world. It is the official conference of the Computer Graphics Society (CGS), a long-standing international computer graphics organization. The Visual Computer is the Official Journal of the Computer Graphics Society.

CGI conference has been held annually in many different countries across the world and has gained a reputation as one of the key conferences for researchers and practitioners to share their achievements and discover the latest advances in Computer Graphics. This year, CGI2022 is still online as the pandemic prevents many researchers to come to Geneva.

The conference CGI is organized from September 12 to September 16, 2022, by MIRALab at the Computer Research Centre (CUI) of the University of Geneva, in Switzerland. All presentations are online.

In addition to the general conference CGI2022, the traditional workshop ENGAGE is again taking place during the first day of the conference. In a parallel session on the first day, we have invited speakers for the workshop in Cultural Heritage (CH) as well as a distinguished CH panel.

This special issue is composed of 37 best papers from papers submitted to CGI 2022. CGI’2022 has received in total 212 submissions and the acceptance rate for the Visual Computer is 17.4%. To ensure the highest quality of publications, each paper has been reviewed by at least three experts in the field, most of them from the editorial board of the Visual Computer.

We would like to express our deepest gratitude to all PC members, Associate Editors of the Visual Computer, and external reviewers, who have provided timely high-quality reviews. We would also like to thank all the authors for their contribution to the conference CGI2022 and particularly for this special issue.
