Besides the commonly known photorealistic rendering, the illustrative image synthesis is widely used among the modern animations, computer games and CAD systems. The main benefit of this approach is that it can use all the instruments of a real artist to guide the user's attention. Research in the field of non-photorealistic rendering varies considerably from the outlining of 3D meshes to the colouring and texturing in artistic ways.

This paper explores the field of the production and usage of these artistic images. These textures generally contain some kind of hatching in which the parameters of the strokes (width, length and style) may vary on the artist's whim. In most cases a tileable texture - a texture which can be tiled beside itself without noticeable break on the contacting edges - is enough to render great scenes. However if we want to render a model with strokes which are evenly distributed in screen space and their style is invariant on the distance of the viewer and the camera we need more advanced structures. One solution is the usage of the self-similar textures. This paper examine the previous work in this subject and presents a new way to create and use them.
