Abstracting Material

Only with this knowledge is it possible to create a valid geometry for all the slats on the surface and tell a fabricator how many to order and how to pre-cut them. In order to find out what really happens, one needs to base the stripe pattern on the bending characteristics of real-world wood strips. Curved surfaces have many geometrical properties that directly influence the options to actually build them (like developability and curvature radii). Most CAD programs can visualise those surface properties, but the designer has to interpret the colourful images and either match the design to the available material or find a suitable material for the given design. If, for example, a curved surface is to be clad with thin strips of wood, it is easy to map a ‘pinstripe’ texture to the respective NURBS model and render a realistic looking but physically wrong image. Speaking from experience, the latter approach is chosen far too often, frequently resulting in awkward and inefficient solutions.
