ICGI 2026 – International Conference on Graphics and Interaction – corresponds to the 33rd conference promoted by the Eurographics Portuguese Chapter – the Portuguese group of the European Association for Computer Graphics. The conference started in the late 80's as a small symposium and has grown in importance each year. 

ICGI 2026 is dedicated to the latest and promising research related to interaction techniques, computer graphics, and their applications, including software, hardware, visualisation, and games. It covers the areas of Computer Graphics, Image Processing, Computer Vision, and Human-Computer Interaction, as well as related fields such as Virtual and Augmented Reality, Modelling, Rendering, Digital Arts, and Information Visualization.
