I'm trying to apply a single texture(a picture file) to each one of these planes created in jit.gl.gridshape. I'm having trouble figuring it out. from the jitter tutorials i can't quite understand how to get the qtmovie into the jit.gl.texture object.

A suggestion into the right direction would be greatly appreciated.

var mywindow = new JitterObject("jit.window","wallpaper");

var mymatrix = new JitterMatrix(4,"char",320,240);

var myqtmovie = new JitterObject("jit.qt.movie", 320, 240);

var myrender = new JitterObject("jit.gl.render","wallpaper");

var mytexture = new JitterObject("jit.gl.texture","wallpapaper");

// create an array of [jit.gl.gridshape] objects randomly arrayed across the window

    myplane[i] = new JitterObject("jit.gl.gridshape","wallpaper");

    myplane[i].scale = [0.05,0.05,0.05];

    myplane[i].color = [0.5,0.3,0.7,0.5];

    myplane[i].position = [Math.random()*2.-1,Math.random()*2.-1];

    // no movie specified, so open a dialog

    else { // read the movie specified

        myqtmovie.read(filename);

    // initialize feedback matrix to all maximum values

    mymatrix.setall(255, 255, 255, 255); 

    myqtmovie.matrixcalc(mymatrix, mymatrix);

    //myqtmovie.matrixcalc(mytexture);

    myrender.erase(); // erase the drawing context

    myrender.drawclients(); // draw the client objects

    myrender.swap(); // swap in the new drawing

Although i do know Java, I know next to nothing about Jitter and Java, but from glancing at your code this line is using a special kind of paper for its drawing context:

Dunno for certain, but could be it, right?

Texture doesn't have an attribute "texture", since that would mean you're

texturing a texture :) To get your matrix data into the texture use

mytexture.matrixcalc() or something. I see you were attempting that before,

but you have to call in on the texture, with the video matrix as the

argument. I'm not sure if you can call it with jit.qt.movie as an argument

while your plane is textured with "picture".

And of course, like Bas pointed out, the context name of your texture has a
