Abstract

In the current report, further developments of a biophysically-based optical model of human skin and a novel method for real-time realistic simulation of human skin are presented. The model utilizes voxelized representation of the tissue and considers spatial/volumetric variations in both structural e.g. surface roughness and chromophore concentration changes in skin layers such as distribution of blood, melanin, collagen, index of blood oxygen saturation, water, pigment content, etc. A Monte-Carlo based approach for simulation of spatially-varying Bidirectional Scattering-Surface Reflectance Distribution Function (BSSRDF) and subsequent physically based computer rendering has been developed. Computer modelling is accelerated by parallel computing on Graphics Processing Units (GPUs) using OpenCL (Open Computing Language). The results of simulation of BSSRDFs, reflectance spectra of human tissues, corresponding colours and 3D rendering examples of human skin appearance are presented and compared with in vivo experimental data obtained during clinical studies.
