 JoonsRenderer is a library for Processing by [Joon Hyub Lee][joonhyublee]. It includes the sunflow java raytracer by [Christopher Kulla][fpsunflower], and the necessary janino compiler by [Arno Unkrig][Arno].  In this gem the JoonsLibrary and sunflower libraries are re-compiled (by Martin Prout) for java-8 and to use janino-3.0.6. The gem is designed to be used with [JRubyArt][jruby_art] or [propane][propane], all you need to do is `require 'joonsrenderer'` and `include_package 'joons'` to use the library.
