Described herein is a method of using a bi-directional texture function (BTF) of an object in design and development of automobiles and other everyday objects. Also described herein is a computer system that uses a BTF of an object to generate a representation of the object which accurately reproduces a visual appearance of the object at a given illumination of the object, where the representation is generated using a render engine.

Method of using a bi-directional texture function

Disclosed herein is a coating material compositions containing (A) a polyhydroxyl group-containing component, (B) a component (B) having on average at least one isocyanate group and having on average at least one of: at least one hydrolyzable silane group of the formula (I): &#x2014;NR&#x2014;(X&#x2014;SiR&#x2033;x(OR')3-x), and at least one hydrolyzable silane group of the formula (II): &#x2014;N(X&#x2014;SiR&#x2033;x(OR&#x2032;)3-x)n(X&#x2032;&#x2014;SiR&#x2033;y(OR&#x2032;)3-y)m, (D) a phosphorus and nitrogencontaining catalyst, and a catalyst (Z), wherein: the catalyst (Z) is selected from zinc and bismuth carboxylates, of aluminum, zirconium, titanium and/or boron chelates and/or of inorganic, tin-containing catalysts, and mixtures thereof; and the coating material composition comprises at least one reaction accelerator (R) which is selected from the group of inorganic acids and/or of organic acids and/or of partial esters of the inorganic acids and/or of partial esters of the organic acids. Processes for producing multicoat paint systems, and coatings obtained from the coating material compositions are also disclosed.
