Not sure if it is possible to load an OBJ at runtime or not. Anyone know? If so, could you please provide an example on how to load an OBJ at runtime?

Certainly is, i’m fairly sure there is an example that does it?

one of the awayphysics examples does it.
BvhTriangleMeshCarTest.as

but the basics are:


import away3d.loaders.parsers.OBJParser;

var _loader : Loader3D = new Loader3D();
_loader.load(new URLRequest('../assets/scene.obj'), new OBJParser());
_loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onSceneResourceComplete); 

private function onSceneResourceComplete(event : LoaderEvent) : void {
var container : ObjectContainer3D = ObjectContainer3D(event.target);
_view.scene.addChild(container);
}

Awesome! Thanks. I am only able to get a small fraction of the examples to compile for me. I was looking at the OBJLoader example which embeds. Thanks so much. This helps out a lot!

You’re gonna want to listen for the AssetEvent.ASSET_COMPLETE event as well. That fires when the individual meshes that comprise the loaded OBJ are processed.

private function LoadEmporiumOBJ() : void
  //Load the Virtual Emporium .OBJ
  {
   Loader3D.enableParser(OBJParser);
   OBJloader = new Loader3D();
   OBJloader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, ScalePosOBJ);
   
   OBJloader.load(new URLRequest("emporium/emporium.obj"));
   view.scene.addChild(OBJloader); 
  }

  private function ScalePosOBJ(event : LoaderEvent) : void
  //rescale the emporium .OBJ
  {
   var mesh : Mesh;
   for (var i : int = 0; i < OBJloader.numChildren; ++i) {
    mesh = Mesh(OBJloader.getChildAt(i));
    mesh.geometry.scale(100);
    //mesh.material = _material
   }
  } 

From a project I’m working on…

(I pretty much nabbed it from the subsurface scattering example, I think)
