Building off of last week’s Box2D and Processing post, I have now posted a short tutorial about the physics package in toxiclibs. The force directed graph example is a simplified version of toxi’s wonderful fidgen project.

I’m pleased to announce I’ve published a first draft of a tutorial about using Box2D in Processing.
Tutorial: http://www.shiffman.net/teaching/nature/box2d-processing/

I’m struggling here to figure out whether I’m (a) creating a Processing Box2D library or (b) simply creating a tutorial and set of examples piggybacking off of JBox2D. For now, I’m doing [...]

Rob Faludi and I are working on a Processing library for Digi’s XBee Series 1 radios. Direct from Rob’s blog:
The library currently facilitates receiving single sample I/O packets in API mode, and returns an object that contains the analog values, digital values, sender’s 16-bit address and RSSI value. The next tasks will be to [...]

I’m pleased to announce that we’re releasing the first version of The Most Pixels Ever, an open-source Java framework for spanning Processing sketches across multiple screens (developed with Chris Kairalla). This is an early version that has many limitations and needs a great deal of improvement, but it does work. The site isn’t [...]

Now, I am rather overdue for an update on my upcoming book. I’ll be posting details soon. However, in the course of finishing up a chapter on String parsing, I discovered that my good friend, the Google SOAP API is no longer being supported (obviously, I’m a little late on the ball [...]

From: http://qrcode.sourceforge.jp/:
“QR Code is a two-dimensional barcode, used widely in Japan. The advantage of QR Code from well-known barcode is larger data capacity (more than 100 bytes, typically) and error correction.”
Thanks to an idea from Tom Igoe, I make a quick and dirty interface for Processing for QRCode decoding. The Pqrcode library page is [...]

A nice article by Peter Hall about the IAC video wall is out in the June issue of Metropolis Magazine. The article mentions our work at ITP on the “most pixels ever” Processing library . . . which we will release soon for beta experimentation!

I know, I know, you’ve been waiting your whole life for this.
Download beta SFTP Processing library (source included in zip).
Download example Processing sketch.
The library uses JSch (Java Secure Channel).
