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.
