This is a small terminal-based renderer using ncurses to render the Mandelbrot set in a standard terminal. By using your mouse you can zoom into more interesting areas, use z to zoom out again and q to quit.
You need to have a correctly defined JAVA_HOME environment as well as the development libraries for ncurses and build essentials for C development. On mac, these can be installed via Homebrew using
brew install ncurses
Afterwards, a
mvn clean package
should suffice.
Note that I only tested the build scripts on a mac.
After a successful build, execute
java -Djava.library.path=target -jar target/main-1.0-SNAPSHOT.jar
While implementing this small application, I strived to prevent over engineering, i.e. not adding code for future improvements (which won't come anyway) by using fancy design patterns, single implementation interfaces, etc.. To keep the overall structure understanadble I also tried to keep the average lines of code per file at around 50.
I've also implemented a parallelized computation of the Mandelbrot set, but even with the smallest terminal font of around 4 pixel, the computation is very fast and time-to-final-image is basically completely based on rendering time which is very, very slow.
