Kaandorp, J. A.2015-10-052015-10-0519871017-4656https://doi.org/10.2312/egtp.19871014In this paper a description is given of the development of data structures by which a large class of fractal objects can be represented using production rules, together with an algorithm to generate these objects. These data structures and algorithm can be used to produce many of the classical, examples of self-similar sets, mentioned for example by Mandelbrot [13]. The algorithm and data structures are part of a fractal system by which production rules can be designed; production rules can be retrieved from and stored in a fractal library.10.2312/egtp.19871014
