    Practical acquisition and rendering of common spatially varying holographic surfaces



    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.
