Abstract

Julia uses the standard iterative algorithm with a maximum iteration depth of 256 to calculate the Mandelbrot and Julia sets. It colors the sets by using a color map which can be customized by the user by specifying colors between which to interpolate. The color map is generated by either interpolating between the colors linearly or by using Catmull-Rom splines to connect the colors in the RGB cube.

User's Guide

Julia has a pretty straightforward user interface. By clicking and dragging in the mandelbrot view one can change the parameter of the julia set. Shift-dragging in either of the views zooms into the specified rectangle. All these parameters can also be set in the inspector.

The Colors menu enable one to use either one of the two default coloring schemes or to compose a customized coloring scheme by using the Merge Panel. Colors can be dragged out of the ColorMerge view and dragged from the Color Panel into the view to an arbitrary position.
