9.1 Truelight Materials9.1.3 CarbonMaterialThe TrueLight CarbonMaterial is a procedural material that simulates carbon surfaces.It offers a special triplanar texturing mode which is useful for objects that do not havean appropriate UV mapping.» Triplanar Carbon Material Settings» Diffuse Color: Sets the shader’s diffuse reflection color. This is the color theshader adopts when the light reflection of the surface is spread to many directions.» Glossy Color: Sets the shader’s colour for glossy reflections. Glossy reflectionsresult from irregularities of a surface at a microscopic level. Reflection behavioris described by the law of reflection which states that the direction of incominglight (incident ray) and the direction of outgoing light reflected (reflected ray) formthe same angle with respect to the surface normal, thus the angle of incidenceequals the angle of reflection. Since a surface is usually not perfectly smooth, theorientation of the normals varies, thus creating a glossy reflection.239
