This demo uses .load method with merge parameter:
view3d.load(name+".iv3d",{merge:true,iid:{pos:[0,0,0]}});
Coodrinate may be passed as extra parameter to load method. This parameter, later, is available in notification and we can move node to required position. Below is sample notification handler:
function(event) { switch(event.code) { case 'merged': { if(event.group && event.iid) { var pos=event.iid.pos; var tm=event.group.enableTM(); mat4.setRow(tm,3,pos); } }break; } }
