We have identified the key aspects that cause such changes, both in terms of the structure of skin and its chromophore concentrations, and rely on the extensive medical and optical tissue literature for accurate data. Our model can be expressed in terms of biophysical parameters, optical parameters commonly used in graphics and rendering (such as spectral absorption and scattering coefficients), or more intuitively with higher-level parameters such as age, gender, skin care or skin type. It can be used with any rendering algorithm that uses diffusion profiles, and it allows to automatically simulate different types of skin at different stages of aging, avoiding the need for artistic input or costly capture processes. 000056161 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/Lightslice$$9info:eu-repo/grantAgreement/EC/FP7/288914/EU/Vanquishing fear and apathy through E-inclusion: \nPersonalised and populated Realistic Virtual Environments for clinical, home and mobile platforms/VERVE$$9info:eu-repo/grantAgreement/EC/FP7/251415/EU/Final Report Summary - GOLEM (Realistic Virtual Humans)/GOLEM 000056161 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000056161 590__ $$a1.542$$b2015 000056161 591__ $$aCOMPUTER SCIENCE, SOFTWARE ENGINEERING$$b17 / 106 = 0.16$$c2015$$dQ1$$eT1 000056161 592__ $$a0.806$$b2015 000056161 593__ $$aComputer Networks and Communications$$c2015$$dQ1 000056161 593__ $$aComputer Graphics and Computer-Aided Design$$c2015$$dQ1 000056161 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000056161 700__ $$0(orcid)0000-0003-3532-6855$$aAliaga, C.$$uUniversidad de Zaragoza 000056161 700__ $$0(orcid)0000-0001-9000-0466$$aJarabo, A.$$uUniversidad de Zaragoza 000056161 700__ $$0(orcid)0000-0002-7503-7022$$aGutierrez, D.$$uUniversidad de Zaragoza 000056161 7102_ $$15007$$2570$$aUniversidad de Zaragoza$$bDpto.
