Using the Processing API

All of the Processing methods, as explained in the Processing Language API, are available as instance methods on your Processing::App. (frame_rate, ellipse, and the 158 others.) This makes it easy as pie to use them within your sketch.

require 'ruby-processing'

class Sketch < Processing::App
  def setup
    color_mode RGB, 1.0
    frame_rate 30
    fill 0.8
  end

  def draw
    triangle(rand(width), rand(height), rand(width), rand(height), rand(width), rand(height))
  end
end

P = Sketch.new(:width => 600, :height => 600, :title => "Triangles Gone Wild")

Because of this method madness, Processing::Apps have a convenience method for searching through them. app.find_method("ellipse") will return a list of the method names that may match what you’re looking for: “ellipse”, “ellipseMode”, and “ellipse_mode”.
