To guarantee physical plausibility of the resulting materials, we use a restricted approach that only allows us to build the shader graphs by using physically safe surface models and physically safe manipulation operators. The tool also allows us to manipulate material properties - fluorescence and polarisation - which can affect object appearance, but are usually missing in other modeling toolsets. Since there is a rising demand for realism of the modelled material appearance among CG content creators, the concept of a restricted shader graph is also useful in the context of common photorealistic renderers.I.3.3 [Computer Graphics]Picture/Image GenerationI.3.5 [Computer Graphics]Physically based modelingI.3.7 [Computer Graphics]ThreeDimensional Graphics and Realism
