Syphon is an OSX framework to share frames between applications. The authors of Syphon, Tom Butterworth and Anton Marini, made it very easy to create Syphon plugins for other languages, frameworks, VJ’ing and mapping tools, etc. So a while ago I wrote a simple Processing library that allowed to send frames out. This was quite useful, but still missing half of the Syphon functionality. With some additional coding, we were able to add the client part, and I just put the new version (0.4) of the Syphon-Processing library up for download (it requires Processing 2.0a4 or newer).

Xavier Hinault recently released a new computer vision library for Processing, based on JavaCV and OpenCV 2: JavacvPro. This is a great contribution to the community, since it appears that the development of the original OpenCV library for Processing has stalled, without moving beyond OpenCV 1.0 support. JavacvPro is based on the very solid JavaCV wrappers by  Samuel Audet, which provide access to the latest version of OpenCV (2.3.1 at the time of writing this), and in fact also allows to use other computer vision frameworks like OpenKinect, and ARToolKit. I did some testing of JavacvPro (version 0.3) on Windows, Mac and Linux, and the results are very promising as I was able to use the library on the three platforms. Xavier has also included many examples in the library package that show how to use it various features.

Thomas Diewald (who is also the author of the excellent kinect library dLibs_freenect, and many Processing pieces) recently created another library for generating realtime fluid simulations in Processing, using either the CPU or the GPU: diewald_fluid. The results are quite amazing, and it is also very fast, specially when using the GPU.

Henri from Mots Cousus released a new library for handling DMX messages in Processing, dmxP512. It is partially based on the proDMX library I wrote a while ago, but supports more DMX hardware (enttec DMX USB PRO and lanbox LCE in its first release) and also adds things like buffering to prevent network/serial congestion. So basically dmxP512 replaces proDMX, which I don’t expect to develop any further.

Here is a new version of the opengl texture library for processing (v0.6.5). In fact, I renamed it to gltexture, and also changed the prefix P* to GL* to avoid conflicts with the core classes of processing. I also fixed a minor bug and added an initial version of the documentation (generated from the code with javadoc).
