[away3d] 3d city - many 3d objects - sketchup models

[Ronaldo]

hi,

I'm trying to create a simple 3d city with some downloaded Google
Sketchup models. For simplicity sake I export them from sketchup in
3ds format, so I dont need to import the textures.

I'm still newbie to away3d, but this is how I think it should be done:

function createBuilding(_URL:String, _x:Number, _y:Number, _z:Number,
_rX:Number, _rY:Number, _rZ:Number,_scale:Number):void
{
     var _loader:Object3DLoader = new Object3DLoader();
     _loader = Max3DS.load(_URL, {material:null});
     _loader.addOnSuccess(loadedBuilding);
}

function loadedBuilding(e:LoaderEvent):void
{
    var object3d:Object3D;
    object3d = e.loader.handle;
    scene.addChild(object3d);
}

function init3d():void {
    createBuilding("models/model1.3ds",x,y,z,rX,rY,rZ,scale);
    ... and so on...
}


1. The problem is I dont know how I'll call the 3d object later, for
interactivity... perhaps I should create a separate class and generate
the models from a object3d... any ideas?


2. Other question: should I try to merge all 3d buildings in a single
3ds file and import it? wouldn't it be easier? but wouldn't it become
cpu intensive?

sorry if this is too confusing.
