Rendering Methods for Iterated Function Systems

TL;DR: An overview of the wide range of spatial model categories, including both empirical and causal (mechanistic) models is presented, an emphasis is put on L-systems and their extensions, viewed as a unifying framework for spatial model construction.

TL;DR: An initial bounding volume estimation method is described, allowing a linear fractal to be rendered given only its iterated, function system, and applications to the rendering of other fractal models are given.

TL;DR: IFS models have become a powerful tool for the construction of fractal sets but present the fundamental disadvantage of providing little control over the global form of the attractor, so free form techniques give a high control over smooth man‐made objects with the use of a set of control points.
