  abstract = {Architectural presentation drawings frequently require the
              drafting of stones, wood patterns, plants and ground materials,
              which, contrary to the majority of drafting tasks, cannot rely on
              repetitious procedures. This paper discusses and illustrates
              computer implemented algorithms which generate graphic
              representations of the above materials. Simulating a process known
              to be applied in practice is certainly a sound approach, and one
              such algorithm, applicable for the derivation of stone walls, is
              presented, But the majority of the algorithms discussed are based
              on a technique which introduces randomly generated disturbances on
              initially regular patterns. The latter algorithms in particular
              have produced highly satisfactory graphic representations, which
              include frequently hand-made qualities.},
