This article addresses the modeling aspects of macrostructured texture synthesis often avoided by other methods. We aim to develop a system that provides an intuitive, interactive, continuous, and easy-to-use control to users during the entire synthesis process. Therefore, we propose efficient new solutions for the following four problems: interactive and easy control of the macrostructure attributes; easy specification of the shapes; controlled deformations and interactions to avoid repetitions. In particular, we use a random technique, which is an important factor in getting more natural-looking structures; use of digitized texture pictures as natural models to guide the synthesis and obtain high-quality results.
