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

Agendas/Minutes
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.

3D Implementation Roadmap
I have done my best to identify what tickets will block others and have created
a roadmap for integrating 3D into the library. I have done so by analyzing the
Processing site and looking through the Processing source.
Items marked 'fix' have been reviewed but need to corrected.
Items marked 'implement' need to be coded, but it also implies writing a good test.
Items marked 'write test' are done, but need a test before they can be reviewed.
A good test should take a peer-reviewer only a few minutes to check and pass on for super-review.
We still need to address what will happen if a ticket isn't complete. This roadmap needs to be
robust enough to not crumble if this occurs.
Release 0.5
Mickael
- Fix camera()
- Write test for camera()
- Fix perspective()
- Write test for perspective()
- Fix P3DMatrixStack
- Write test for P3DMatrixStack
Andor
- Write setUniformf()
- Write setUniformi()
- Write setUniformMatrix()
- Write test for frustum()
- Write test for PMatrix3D trans(), mult(), set(), apply(), scale()
Anna
