SUMMARY:Affordable Spectral Measurements of Translucent Materials
DESCRIPTION:Technical Papers\n\nAffordable Spectral Measurements of Transl
 ucent Materials\n\nIser, Rittig, Nogué, Nindel, Wilkie\n\nWe present a spe
 ctral measurement approach for the bulk optical properties of translucent 
 materials using only low-cost components. We focus on the translucent inks
  used in full-color 3D printing, and develop a technique with a high spect
 ral resolution, which is important for accurate color reproduction. We ena
 ble this by developing a new acquisition technique for the three unknown m
 aterial parameters, namely, the absorption and scattering coefficients, an
 d its phase function anisotropy factor, that only requires three point mea
 surements with a spectrometer. In essence, our technique is based on us fi
 nding a three-dimensional appearance map, computed using Monte Carlo rende
 ring, that allows the conversion between the three observables and the mat
 erial parameters. Our measurement setup works without laboratory equipment
  or expensive optical components. We validate our results on a 3D printed 
 color checker with various ink combinations. Our work paves a path for mor
 e accurate appearance modeling and fabrication even for low-budget environ
 ments or affordable embedding into other devices.\n\nRegistration Category
