How well do various digital appearance representations perform at communicating the "touch and feel" of materials?
Many real-world surfaces are covered in fine scratches that diffract light in colorful ways. Our model seamlessly transitions between ray optics and wave optics to recreate this intricate effect.

A reflectance model for pile fabrics that you can "draw on" using your fingers, like velvet or Alcantara.
Computer Graphics Forum (Proc. EUROGRAPHICS), 2011.
We define the problem of physically displaying material appearance, and demonstrate a conceptual device that exhibits precisely controllable reflectance distributions by generating waves on a water surface.
