Mobius Transformations Overview
Several of the Fractal Science Kit fractal generator built-in programs make use of Mobius transformations, also called linear fractional transformations. Mobius transformations are complex transformations in the form:
f(z) = (A*z + B) / (C*z + D)
The numbers A, B, C, and D are complex numbers. The input to the function (z) and the function result are both complex.
Mobius transformation can be classified as 1 of 4 types: elliptic, hyperbolic, loxodromic, or parabolic.
While the understanding of Mobius transformations is not a prerequisite to using the application, it is an interesting and rewarding area of mathematics that can be used to produce beautiful fractals and is highly recommended.
