1 Introduction Modelling the appearance of real-world materials in a physically faithful fashion is crucial for predictive rendering. This, however, is a challenging task: Many materials comprise complex fine-grained geometries that largely drive their macro-scale appearances. Traditionally, material reflectance is specified using spatially varying BRDFs (SVBRDFs) or Bidirectional Texture Functions (BTFs).
