JRubyArt is a ruby wrapper for processing-3.3.7. Create processing sketches in ruby using regular ruby-2.4+ syntax, and use the magic JRuby to run them. You can use both rubygems and and regular processing libraries in your sketches. Features run, watch and live modes (uses pry).
In general where there is a choice of using a java (processing) method or a regular ruby method you should choose the ruby method (eg use
rand in place of
random). Further you should prefer to use
Vec3D instead of processings
PVector class. Processing has a number of convenience methods which are not needed in ruby (eg ‘pow’ use
** in JRubyArt) and some static methods have not been implemented in JRubyArt. For the processing
map method prefer
map1d (see example) or use
p5map if you must. Another thing to watch is
color which is implemented differently in JRubyArt (see example).
