Abstract
Iterated Function Systems are typically defined
through sets of contractive linear transformations.
The theory of Iterated Function Systems is based on
the contractivity but not on the linearity of the
defining functions. Piecewise bilinear distortions
of grids are used in this work to specify nonlinear
Iterated Function Systems. Nonlinear Iterated Functions
Systems are characterized by a higher degree of
flexibility and greater modeling capability than their
linear counterparts. Modeling and rendering aspects are
discussed. Limit sets of 2D nonlinear Iterated Function
Systems are represented by approximating point sets.
Limit sets of 3D nonlinear Iterated Function Systems
are either rendered by displaying approximating point
sets (z-buffer approach) or through ray tracing an
approximate set of 3D solids. Example images of a
test implementation are presented.
