+ <h2>Abstract:</h2>
+ <blockquote>
+   Typical material systems are based on a collection of properties 
+   that are set on a per–object or per–surface basis usually by evalua- 
+   tion of a description ﬁle at run–time. Shading of hit points is then 
+   implemented by interpreting these properties. In order to be able 
+   to support a large feature set, different code paths need to be cre- 
+   ated, e.g. for reﬂection and refraction effects. Conditions for the 
+   branches associated with these fragments of functionality need to 
+   be evaluated for each shaded ray, which may degrade performance 
+   considerably. Material speciﬁc optimization opportunities are also 
+   missed out by having a generic function for all material conﬁgura- 
+   tions.  We propose the use of run–time code generation for materials.
