OutputMatrix in Javascript (jit.gl.text)

it's a little tricky, but possible. you have to create a JitterListener object to listen for the matrixoutput events.

for your case, i would modify the script to create a single jit.gl.text object, and instead store an array of matrices when you receive them in the callback function.

autowatch = 1

//create arrays for text
add_letters=[]
add_graph=[]



//erase all text
function clear() {
    add_letters=[]
    add_graph=[]
}

var letters = new JitterObject("jit.gl.text","ctx");
var lstnr = new JitterListener(letters.name, callbackfun);
letters.position=[0.,0.,0.]
letters.mode=("3d")
letters.matrixoutput=(1)
letters.automatic = 0;

//insert text
function letter(l) {

    add_letters.push(String.fromCharCode(l));
    letters.text(String.fromCharCode(l))
    letters.drawraw();
}

function callbackfun(event)
{
    if (event.eventname == "matrixoutput") {
        // create javascript matrix from matrixoutput event arg
        var lmat = new JitterMatrix(event.args[0]);
        add_graph.push(lmat);
        
        post(event.args[0]+"\n");
        outlet(0, "jit_matrix", event.args[0]);
    }
}
callbackfun.local = 1;
