The programming uses the following external code:
jit.gl.hap – Rob Ramirez
ab.hsflow.jxs – Andrew Benson
jit.openni – DiabloDale
cv.jit – Jean-Marc Pelletier
Is 8 x 8 enough?
Adapted from a tutorial by Darwin Grosse
This Max tutorial, from Cycling 74, connects the builtin-camera to a Push display matrix, using Midi sysex codes. https://cycling74.com/wiki/index.php?title=Push_Programming_Oct13_03
If you set the frame rate high enough, you can clearly see motion.
I thought it would be interesting to display icons at this resolution, but its not very impressive. Here’s an example.
The 8 x 8 version is on the left. The original, on the right, is 57 x 57. Another problem is that the RGB quality of the Push is not very accurate for anything beyond primary colors. Here is the modified version of the patch.

A sample accurate version of the Max metro object.
Detects state change when a phasor goes from one to zero. I first saw this in a patch by jhno. Here is a tutorial by Cycling 74: https://cycling74.com/wiki/index.php?title=MSP_Sequencing_Tutorial_1:_Audio-Rate_Sequencing
This patch is used as a clock in an RTTY (frequency shift keying) project. https://reactivemusic.net/?p=8893. It uses the count~ object instead of phasor~ because its easier to restart the clock at zero phase.

You may notice similarities to dude837’s Boids sonificiation patch. https://reactivemusic.net/?p=18388 The swarm was replaced by drunken dots.

Audio data for Visualization and Introduction to Open GL
Generally, visualizations will track amplitude, pitch – or any characteristic of audio that is changing over time.

Next week we will look at some of your work in progress for the midterm assignment (that will be due by March 31. Please be ready to demonstrate something or you will have to listen to me again.
