7.1 Truelight Materials7.1.18 PlasticThe Plastic material is designed to simulate diffuse plastic or leather surfaces.» Plastic 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)form the same angle with respect to the surface normal, thus the angle ofincidence equals the angle of reflection. Since a surface is usually not perfectlysmooth, the orientation of the normals varies, thus creating a glossy reflection.» Roughness: The roughness parameter defines the microscopic roughness of a269
