With the need to create distinction from conventional car design, concept car design for Renault EOLAB Concept, Audi Aicon Concept, BMW vision next 100, have extensive use of algorithms with complex shapes and patterns. Parametric design applications can be found on car grilles, wheels and other details, as well as three-dimensional textures for interiors. Although inherent design logic with fading and repetition of elements is simple, it can not be easily achievable using conventional 3d modeling methods.
