Appearance

We predict the appearance of materials from their physical microstructure

The appearance of a material is largely determined by the microstructure of its surface and the particles beneath its surface. We construct mathematical models for predicting material appearance based on surface properties and particle content. We also investigate the challenges of fast and accurate rendering of material appearance. The goal is to interactively compute realistic images of real-world materials.

About the project

Modeling and rendering of material appearance is highly challenging due to the nontrivial physical composition of most materials and due to the complex nature of light. We need mathematical models at a scale macroscopic enough to describe light-material interaction useful for graphical rendering of a scene, but we also need the complexity to be high enough to produce realistic images. This project is all about striking the right balance.
