julia/mandel

Calculate and graphically display Julia and Mandelbrot sets

Authored and Contributed by: Ronald Joe Record
Description: Julia and mandel are X11 clients. Julia can be used to display the popular Julia sets. These sets are calculated by iterating the map z -> z^2 + c where z and c are Complex numbers, c a specified parameter and z the initial condition. Mandel calculates and displays the Mandelbrot set. This is done by iterating the same map, z -> z^2 + c, but here the initial condition is held fixed at the origin and c is varied over a specified subset of the Complex plane.
Build: To build the julia and mandel binaries, either use the Imakefile or the sample makefile - Makefile.std. To build with the Imakefile, first type "xmkmf" or "imake -DUseInstalled -I/usr/lib/X11/config" if your system doesn't have xmkmf. Then just type "make" and the julia binary will be built. To create the mandel binary, type "ln julia mandel" as it is just a link. The manual pages can be formatted by typing "nroff -man julia.man > julia.doc" and "nroff -man mandel.man > mandel.doc".
Install: To install julia, copy the julia binary to the desired location (the sample makefiles put it in /usr/local/bin) Copy the formatted man page to wherever you keep your local doc (i use /usr/man/cat.LOCAL for imaging software), then add that location to your MANPATH.
Productivity: These programs and others like them are probably responsible for more CPU cycles than any other single application.
Safety: I have used these for years without harm.
Work Planned: None
Documentation: manual pages.
Verification: Execute any or all of the shell scripts provided in /usr/skunk/lib/julia and /usr/skunk/lib/mandel.
