Hi I am very interested to work with this js glvideotrail.js.

I wonder if it is posible to use it in separate render context.

Either by achieving this effect with jit.gl.multiple with a texture argument.

or be able to capture it in a jit.gl.node

in any cases to incorporate this effect in a big patches with other effect.

Have you tried jit.gl.pass @fxname smear @ erase color 1. 1. 1. 0.1

Max 7 only.


finally i find this way with jit.gl.multiple and tap.jit.delay.

I looking for create de delay in open gl , any idea?

you can capture jsglvideotrails to a gl.node, but you have to make some changes first.

since you've already created a render and window context, you need to remove those objects from the js file. you've correctly created a gl.node with the same name as the context that the js videoplanes are drawing to, so that's good.

another caveat, is you can't render in non-automatic mode when capturing to texture, so you must set automatic=1, and remove the videoplane draw call. i've pasted in the changed functions below:

// our jit.gl.videoplane objects and associated attribute arrays
var current = 0;
var vcount = 32;
var vspacing = 1.;
var vrotate = 0.;
var vscale = 1.;
var vbrightness = 2.;

var aplanes = new Array();
var apos = new Array();
var arot = new Array();
var ascale = new Array();

count(32);

function count(c) 
{
    if (c=vcount)
        current = 0;
    outlet(0,"bang");
}



// our jit.gl.videoplane objects and associated attribute arrays
var current = 0;
var vcount = 32;
var vspacing = 1.;
var vrotate = 0.;
var vscale = 1.;
var vbrightness = 2.;

var aplanes = new Array();
var apos = new Array();
var arot = new Array();
var ascale = new Array();

count(32);

function count(c) 
{
	if (c=vcount)
		current = 0;
	outlet(0,"bang");
}



then you simply trigger your movie with the same metro that triggers your rendering, and you should be good:

i posted an example of capturing with node and JS:
