unfortunately i don’t know much about jit.matrix… i would guess it will come as an array to javascript, than you will have to do a “for” loop in your script to go through all cells..

if you post a simple example patch, with a jit matrix being filled and than dumped out, would be super easy to help ( :

might be from your interested this simple javascript example i put in this topic, and surely would help you to understand some stuff in javascript: http://cycling74.com/forums/topic.php?id=25125

good luck in your programming journey !

i am trying to learn some javascript and want to understand how to get a jitter-matrix input into js-code. As an example in the Jitter tutorial 46: In the attached JS-File there is a jit.noise object generated for the attractors.

// create a [jit.noise] object for attractor generation
var attgen = new JitterObject(“jit.noise”);
attgen.dim = ATTRACTOR_COUNT;
attgen.planecount = 3;
attgen.type = “float32″;

if I don’t want random attractor points, but generate a 3plane float32 matrix in Jitter, how can I then feed this jitter-generated-matrix into the JS-File and replace the jit.noise with it?

create a named jitter matrix in your patch:
[ jit.matrix mymatrix 4 char 80 60 ]

reference it in js:
var mat = new JitterMatrix("mymatrix");
