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