Design principle CNC technology allows graphical representations to be produced using line structures of different local density and depth. This is based on a relatively homogeneous basic structure (for example parallel lines, concentric circles) which consist of non-inters- ection elements and which fills presentations plane. This line structure forms the background. Textures are transformed according to defined mathematical algorithms, i.e. they are differentiated from the background structure by changes in the distance between the lines and in the direction of lines (nicks, curves). The lines remain non-intersecting, however, even after whole series oftransformations. Different editing planes give rise to a greater plasticity of the space and the transfer of superordinate structural information allows the representation of most elements of planar geometry, such as print characters or hatching. The creative versatility of this principle lies in the combination of individual transformation algorithms (sequence, foreground and background, depth and width). The following examples are intended to provide a small insight into the almost unlimited possibilities. Three such textures are included in our standard program. Let them inspire you to design your own textures.
