Hi All
Pretty new to this 3d stuff so bare with me. I am working on a project lets call it model viewer. I need to be able to load models and then unload them. Due to the nature I need the model completely removed from memory. I seem to be removing a fair amount of memory but not all of it. I start with 27mb before loading model. I hit 89mb with loaded model. Then after running destroy() I end up with 59mb. Any help would be great.

_view = new View3D();
   _view.antiAlias = 2;
   _view.backgroundColor = 0x333333;
   
   _camera = _view.camera;

_loader = new Loader3D(false);
_loader.addEventListener(AssetEvent.ASSET_COMPLETE,onAssetComplete);   _loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE,onResourceComplete);
_loader.load(new URLRequest(_path+_url), new AssetLoaderContext(true));

private function onAssetComplete(ev : AssetEvent) : void
  {
   trace("asset "+ev.asset)

    _mesh = Mesh(ev.asset);

   disposemodel(_loader)
   
   
   
   try {
    new LocalConnection().connect('foo');
    new LocalConnection().connect('foo');
   } catch (e:*) {}
  }
  
  public function disposemodel(model:Loader3D):void
  {
   _group.removeChild(_loader);
   _view.scene.removeChild(_group);
   _view.camera.disposeAsset();
   _view.camera.dispose();
   _camera.disposeAsset();
   _camera.dispose();

Same old story, have you tried to force GC? Because maybe you are disposing correctly but GC runs later. If you are sure that something is stuck in memory use profiler and the loitering object functionality to find out what’s remaining in memory.

Yes, I do force gs its in the code above. I have also let it run for an extended period to see if it clears out on its own.

I think more what I am asking, since I am new to away3d is am I correctly disposing of the model, assets, view etc. Is there a better way? Am I maybe not disposing of something or not doing it correctly correctly? I read something about an assetlibrary and a few other things that I dont understand or could not get to work.

The AssetLibrary is used to store loaded models, but in your code you’re not using it because you instatiate Loader3D with “new Loader3D(false)” so you don’t have to dispose the AssetLibrary in this case.

thanks, is there any benefit in my case to using the AssetLibrary? is the rest of my dispose code good? am I missing or could improve anything?
