Two words seldom heard in the same sentence are Ruby and Graphics… at least without laughter soon following. We've heard it all before: Ruby is too slow; real graphics are done in C, CplusPlus, or Assembler; there's no support for OpenGL in Rails.
The excuses may be many, but the reasons are few. With JRuby we have access to a tool that bridges the worlds of Java and Ruby. With Java Native Interface (JNI) we have a bridge to the world between the low level interfaces that rule the bitmapped and bump-mapped world. Combining the two allows us to use a language we love to tackle problems that used to be the domain of esoteric solutions in low level languages.
This talk explores how to use our favorite scripting language and the breadth of the Java ecosystem to generate interactive visualizations with less pain and fewer segfaults than we've come to expect for using Ruby to tackle "low level" problems.
