8.1 Truelight Materials8.1.22 TriplanarMaterialThe TrueLight TriplanarMaterial simulates diffuse plastic or leather surfaces while offeringa special triplanar texturing mode for objects that do not have an appropriate UVmapping. With the bump and texture channel many diffuse surface structures can besimulated.» Triplanar Material» 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, the237
