Jitter in javascript

Why would you write Jitter code inside a js object?

  • Math expressions
  • File IO
  • Borrowed code
  • You’re just that way

There are three Jitter javascript tutorials (built in to Max) 45-47

The Max javascript documentation is generally far flung. A helpful reference by Tim Schenk http://reactivemusic.net/?p=17445

Here’s an example to get started with. It downsamples a movie and changes the background color. Something I often dream about.

Mystery surrounds jit.ameba.

From earlier (Max 5)  Cycling 74 documentation https://docs.cycling74.com/max5/refpages/jit-ref/jit.ameba.html:

“The jit.ameba object began life as a completely failed attempt at a linear interpolation object. As the Oblique Strategies say, “Honor thy error as a hidden intention.” If you’re interested in linear interpolation objects, try the jit.plur object. Otherwise, please enjoy the mess.”

Horizontal and vertical quantization

What actually does that mean?

“This is a pixilation (resampling) trick. The help file admits this was supposed to be something else, but didn’t work. Needs a spell check too, but pretty interesting. ”
