Course Description
How do you know a sidewalk is slippery or tell wax from metal by just looking? This course introduces two key attributes of material appearance that define how materials look: translucency and gloss. Students discover how these features appear in everyday objects, their importance in science and industry, and how our eyes and brain work together to perceive them. We look at the factors, both physical and psychological, that create these impressions, challenges we face when reproducing them, and what questions still remain unanswered. The course goes beyond an earlier version that focused on translucency to explore gloss and how these two elements affect each other. Handout notes and a carefully chosen reading list are provided for further learning.
Intended Audience: students, PhD candidates, postdoctoral researchers, engineers, designers, artists, and other professionals dealing with modeling, measuring, and manufacturing or rendering different materials.
Davit Gigilashvili has a PhD in computer science from NTNU. The topics of his doctoral research were material appearance and translucency perception. Gigilashvili has co-authored more than 30 articles on these topics, including a comprehensive state-of-the-art review on translucency perception that is published in the Journal of Vision and a chapter on gloss and translucency perception in Fundamentals and Applications of Colour Engineering.
