What is it about?
We have developed a method to recreate how materials change their appearance over time, focusing on things like rusting, decaying, melting, and weathering. Unlike previous approaches that focus on separating how things look (appearance) and how they move (motion), we center on capturing changes in how materials themselves evolve visually.

Why is it important?
This area is close to our daily life but rather under-explored, as appearances are essential to our visual perception and many factors are changing the appearances around us every second. We open the door to a robust framework of modeling such phenomena through observed data and lay the foundation for future research by collecting and releasing the first dedicated dataset.
Perspectives
Metal and rusty metal are two materials commonly used in game and film production. While working on this project, I aimed to answer at least one key question: how can we find a tool to digitally bridge these two materials? I hope this work offers a fresh perspective for analyzing these dynamic appearances.
