ABSTRACT
We present a novel approach to measure the appearance of commonly found spatially varying holographic surfaces. Such surfaces are made of one dimensional diffraction gratings that vary in orientations and periodicities over a sample to create impressive visual effects. Our method is able to recover the orientation and periodicity maps simply using a flash illumination and a DSLR camera. We present real-time renderings under environmental illumination using the measured maps that match the observed appearance.

Acquiring spatially varying appearance of printed holographic surfaces
We present two novel and complimentary approaches to measure diffraction effects in commonly found planar spatially varying holographic surfaces. Such surfaces are increasingly found in various decorative materials such as gift bags, holographic papers, ...
Rendering specular microgeometry with wave optics
Simulation of light reflection from specular surfaces is a core problem of computer graphics. Existing solutions either make the approximation of providing only a large-area average solution in terms of a fixed BRDF (ignoring spatial detail), or are ...
Practical Acquisition and Rendering of Diffraction Effects in Surface Reflectance
We propose two novel contributions for measurement-based rendering of diffraction effects in surface reflectance of planar homogeneous diffractive materials. As a general solution for commonly manufactured materials, we propose a practical data-driven ...
