Eurographics 2003 Short Paper Proceedings, pp. 301-306, 2003.<br /> <br /> == DOI ==<br /> <br /> == Abstract ==<br /> The look of a non-transparent material is determined by its bidirectional reflection distribution function (BRDF).<br /> To design 3-D objects for example for games or animation films thus includes to design BRDFs. However, as func-<br /> tions defined on a four-dimensional domain, these form a vast space that is very difficult to explore interactively.<br /> Typically, the infinite number of degrees of freedom is reduced to a tractable handful of parameters by introducing<br /> simplified physical models or heuristic approximations such as Phong’s. As the complexity of such approaches<br /> increases, they become difficult to master for a human operator. Even if many parameters are made accessible,<br /> an infinite variety of useful and/or interesting BRDFs remains hidden and inaccessible. We therefore propose a<br /> method of constructing BRDFs through genetic programming with a human operator making choices based on his<br /> or her preferences. With the pixel shader programmability of modern graphics cards this can be performed in real<br /> time.<br /> <br /> == Extended Abstract ==<br /> <br /> == Bibtex == <br /> <br /> == Used References ==<br /> 1.
