Three Dimensional Fractal Mappings
Years ago, many fractal enthusiasts viewed these intricate and majestic patterns and thought "Wouldn't this be incredible in 3-D?". Dozens of methods have been developed to view fractals in an arbitrary number of dimensions. Quaternions are 3D shadows of 4D Julia Sets, which, if sliced in a plane, reveal the corresponding 2 dimensional Julia Set.
