Constructor Details

#initialize(options = {}) ⇒ App

It is ‘NOT’ usually necessary to directly pass options to a sketch, it gets done automatically for you. Since processing-2.0 you should prefer setting the sketch width and height and renderer using the size method, in the sketch (as with vanilla processing), which should be the first argument in setup. Sensible options to pass are x and y to locate sketch on the screen, or full_screen: true (prefer new hash syntax)
