IFSs were conceived in their present form by John E. Hutchinson in 1981 and popularized by Michael Barnsley's book Fractals Everywhere. IFSs provide models for certain plants, leaves, and ferns, by virtue of the self-similarity which often occurs in branching structures in nature.— Michael Barnsley et al. Meer weergeven In mathematics, iterated function systems (IFSs) are a method of constructing fractals; the resulting fractals are often self-similar. IFS fractals are more related to set theory than fractal geometry. They were introduced … Meer weergeven Formally, an iterated function system is a finite set of contraction mappings on a complete metric space. Symbolically, Meer weergeven Sometimes each function $${\displaystyle f_{i}}$$ is required to be a linear, or more generally an affine, transformation, and hence represented by a matrix. However, IFSs may also be built from non-linear functions, including projective transformations Meer weergeven The diagram shows the construction on an IFS from two affine functions. The functions are represented by their effect on the bi-unit square (the function transforms the outlined square into the shaded square). The combination of the two … Meer weergeven Hutchinson showed that, for the metric space $${\displaystyle \mathbb {R} ^{n}}$$, or more generally, for a complete metric space Meer weergeven PIFS (partitioned iterated function systems), also called local iterated function systems, give surprisingly good image … Meer weergeven Very fast algorithms exist to generate an image from a set of IFS or PIFS parameters.
