Projective Texturing

now im trying to add to the loop an opengl object from outside js.
my logic was that if only i add the gl obejct instance name to the
//
for(var i=0; i < objects.length; i++) {
var model_to_world = modelToWorldTransform(objects[i]);
shader.param("modelToWorld", model_to_world);
objects[i].draw();
}
//
but if i recall it isnt possible to share a render context in js and in max
togther. at least i couldnt find an example for such. is this possible? hope
im getting thru.
