Project Details

Processing is an open source programming language and environment for people who want to program images, animation, and interactions. Processing is an alternative to proprietary software tools in the same domain.

Processing.js will:

  • enable Processing users to take advantage of the full power of the open web
  • serve as a forcing function to drive improvements in key aspects of Mozilla products and technologies, including; JavaScript, Camvas Functionality, applications of Bespin, Ubiquity, Multi-Touch and others

Tools

  1. Processing (Java) @ http://Processing.org
  2. Processing JS code @ http://ProcessingJS.org
  3. Minefield builds for WebGL (build your own or http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/). See also Vlad's post on this: http://blog.vlad1.com/2009/09/18/webgl-in-firefox-nightly-builds/

  6. HasCanvas, a Processing JS IDE @ http://HasCanvas.com

Learning

  1. Recent interview with creators of Processing about the language and its future
  2. Download the Java version of Processing @ http://processing.org/download/
  3. Look at what Processing Java is capable of @ http://processing.org/exhibition/
  4. Look at what has been done with Processing JS so far @ http://processingjs.org/exhibition & @ http://hascanvas.com/#open-about
  5. Read Processing articles "Getting Started" & "Coordiante System & Shapes" @ http://processing.org/learning/gettingstarted/ & @ http://processing.org/learning/drawing/
  6. Experiment around with the Processing Java app, use the Basic Examples @ http://processing.org/learning/basics/ and make something cool, interesting, wacky, where-ever your experiment takes you.
  7. Test whether you can re-create your sketch by copying your code to http://hasCanvas.com You can share your work so others can see what you have done, you can also use hasCanvas to embed your visualization in your web site / blog.

Processing.js 0.1 Code status

This table is for students who have 0.1 code that needs to be pushed into the processing.js library
Please add your functions below that require review by Al.
A new format for submitting work for review and a bug tracker will be implemented by 0.2 release time
How to use this chart:

  • function: your functions name or function you modified
  • name: your name
  • code link: a link to the code snippet or diff file if you had to change a function
  • state: r?, needs review by Al. r-, reviewed by Al and not fit for check-in yet. r+, reviewed by Al and work looks ok. checked-in, reviewed by Al and checked into the library.
  • comments: comments you can put for Al or he can put regarding his review of your work.
