We enhance existing structured light phase shifting methods by using trigonometric moments.
Real-Time Rendering of Wave-Optical Effects on Scratched SurfacesZdravko Velinov*, Sebastian Werner*, Matthias B. Hullin (* joint first authors)
Computer Graphics Forum 37 (2) (Proc. EUROGRAPHICS), 2018.
In this paper, we develop closed-form solutions for illuminating our iridescent scratch model with spherical and polygonal area light sources, bringing this effect within reach of real-time applications for the first time.
A Quantitative Platform for Non-Line-of-Sight Imaging ProblemsJonathan Klein, Martin Laurenzis, Dominik L. Michels, Matthias B. Hullin
In Proceedings of British Machine Vision Conference (BMVC 2018), Northumbria University, Newcastle, UK, September 3-6, 2018, 2018.
In this paper, we present a reference database of time-resolved light echoes for non-line-of-sight sensing.
Digital Transmission of Subjective Material AppearanceRodrigo Martín, Michael Weinmann, Matthias B. Hullin
Proc. WSCG, 2017.
How well do various digital appearance representations perform at communicating the "touch and feel" of materials?
Scratch Iridescence: Wave-Optical Rendering of Diffractive Surface StructureSebastian Werner*, Zdravko Velinov*, Wenzel Jakob, Matthias B. Hullin (* joint first authors)
ACM Transactions on Graphics 36(6) (Proc. SIGGRAPH Asia), 207:1--207:14, 2017.
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.
An Interactive Appearance Model for Microscopic Fiber SurfacesZdravko Velinov and Matthias Hullin
Proc. Vision, Modeling and Visualization, Bayreuth, Germany, 2016.
A reflectance model for pile fabrics that you can "draw on" using your fingers, like velvet or Alcantara.
Dynamic Display of BRDFsMatthias B. Hullin, Hendrik P. A. Lensch, Ramesh Raskar, Hans-Peter Seidel, Ivo Ihrke
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.
