1-systems are a mathematical formalism which used to be proposed by way of Aristid 1indenmayer in 1968 as a starting place for an axiomatic thought of advance ment. The concept speedily attracted the eye of machine scientists, who investigated 1-systems from the perspective of formal language conception. This theoretical line of study used to be pursued very actively within the seventies, leading to over a thousand courses. a distinct study path used to be taken in 1984 through Alvy Ray Smith, who proposed 1-systems as a device for synthesizing practical photographs of crops and mentioned the connection among 1-systems and the concept that of fractals brought by means of Benoit Mandel brot. The paintings by way of Smith encouraged our reviews of the applying of 1-systems to special effects. initially, we have been attracted to difficulties: • Can 1-systems be used as a pragmatic version of plant species present in nature? • Can 1-systems be utilized to generate pictures of a large category of fractals? It grew to become out that either questions had affirmative solutions. to that end we came across that 1-systems will be utilized to different parts, similar to the new release of tilings, replica of a geometrical paintings shape from East India, and synthesis of musical ratings in accordance with an interpretation of fractals. This publication collects our effects regarding the graphical functions of- structures. it's a corrected model of the notes which we ready for the ACM SIGGRAPH '88 path on fractals.
