The Group included Koki Nagano, Graham Fyffe, Oleg Alexander, Paul Debevec from USC Institute for Creative Technologies, Jernej Barbič, Hao Li from University of Southern California, Abhijeet Ghosh from Imperial College London use a 10-micron resolution scanning technique to measure several in vivo skin samples as they are stretched and compressed in different directions, quantifying how stretching smooths the skin and compression makes it rougher.
We tabulate the resulting surface normal distributions, and show that convolving a neutral skin microstructure displacement map with blurring and sharpening filters can mimic normal distribution changes and microstructure deformations. We implement the spatially-varying displacement map filtering on the GPU to interactively render the effects of dynamic microgeometry on animated faces obtained from high-resolution facial scans.
