Hi all!

I’m new to away3D. I’m trying to do a what I suppose is a simple task, but I can’t get it to work.
I would like to load a model and then load a texture and apply it to the model.
It won’t work. What am I doing wrong?
Here’s my code:

import away3d.containers.View3D;
import flash.events.Event;
import flash.display.MovieClip;
import away3d.containers.View3D;
import flash.geom.Vector3D;
import away3d.materials.ColorMaterial;
import away3d.materials.TextureMaterial;
import away3d.textures.BitmapTexture;
import away3d.events.LoaderEvent;
import away3d.loaders.Loader3D;
import away3d.loaders.parsers.Parsers;
import flash.display.Sprite;
import flash.events.Event;
import flash.net.URLRequest;
import flash.display.BitmapData;
import flash.display.Loader;
import flash.display.Bitmap;

var view:View3D;
var modelLoader:Loader3D;

var myBitmap:Bitmap
var textureLoader:Loader
var material:TextureMaterial

function initView()
{
 view = new View3D();
 view.backgroundColor = 0x666666;
 //position and target the camera
 view.camera.position = new Vector3D(0,50,-80);
 view.camera.lookAt(new Vector3D());
 //add the view to stage;
 addChild(view);
 loadTexture()
}

function loadTexture()
{
 textureLoader = new Loader()
 textureLoader.load(new URLRequest("teapot.jpg"));
 textureLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, textureLoaded);
}

function textureLoaded(evt:Event):void 
{ 
 var bmp01:Bitmap = textureLoader.content as Bitmap
 myBitmap = new Bitmap(bmp01.bitmapData)
 myBitmap.smoothing = true
 material = new TextureMaterial(new BitmapTexture(myBitmap))
 loadModel();
}

function loadModel()
{
 Parsers.enableAllBundled();

 modelLoader = new Loader3D();
 modelLoader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, modelLoaded);
 modelLoader.addEventListener(LoaderEvent.LOAD_ERROR, loadError);
 modelLoader.load( new URLRequest('teapot.obj') );
}

function modelLoaded(evt:LoaderEvent):void
{
 modelLoader.removeEventListener(LoaderEvent.RESOURCE_COMPLETE, modelLoaded);
 modelLoader.removeEventListener(LoaderEvent.LOAD_ERROR, loadError);
 modelLoader.material = material
 view.scene.addChild(modelLoader);
 this.addEventListener(Event.ENTER_FRAME, render);
}

function loadError(evt:LoaderEvent):void
{
 trace('Could not find', ev.url);
 modelLoader.removeEventListener(LoaderEvent.RESOURCE_COMPLETE, modelLoaded);
 modelLoader.removeEventListener(LoaderEvent.LOAD_ERROR, loadError);
 modelLoader = null;
}

function render(ev : Event):void
{
 modelLoader.rotationY +=  2;
 view.render();
}

initView();

Try this:

private var _teapot:Mesh;
private var _teapotMaterial:TextureMaterial;

[Embed(source="/../assets/teapot.obj", mimeType="application/octet-stream")]
private var TeapotModel : Class;
[Embed(source="/../assets/teapot.jpg")]
private var TeapotTexture : Class;

var bitmapTeapotTexture:BitmapTexture = new BitmapTexture(new TeopotTexture().bitmapData);
_teapotMaterial= new TextureMaterial(bitmapTeapotTexture);

AssetLibrary.enableParser(OBJParser);
AssetLibrary.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetComplete);
AssetLibrary.loadData(new TeapotModel (), null, "Teapot");

private function onAssetComplete(event:AssetEvent):void{
 _teapot = event.asset as Mesh;
 _teapot.material = _teapotMaterial;
 _view.scene.addChild(_teapot);
}

Thanks for the reply!

I’m not using flex i’m only using flash professional. I’m writing all the code directly in flash.

But I have been getting somewhere. Now my only problem is the applying of the bitmap to the material. I’m getting the error:“1067: Implicit coercion of a value of type flash.display:Bitmap to an unrelated type flash.display:BitmapData.”

Here is my updated code:

import away3d.containers.View3D;
import flash.events.Event;
import flash.display.MovieClip;
import away3d.containers.View3D;
import flash.geom.Vector3D;
import away3d.materials.ColorMaterial;
import away3d.materials.TextureMaterial;
import away3d.textures.BitmapTexture;
import away3d.events.LoaderEvent;
import away3d.loaders.Loader3D;
import away3d.loaders.parsers.Parsers;
import flash.display.Sprite;
import flash.events.Event;
import flash.net.URLRequest;
import flash.display.BitmapData;
import flash.display.Loader;
import flash.display.Bitmap;
import away3d.entities.Mesh;
import away3d.containers.ObjectContainer3D;
import away3d.lights.PointLight;
import away3d.materials.lightpickers.StaticLightPicker;

var view:View3D;
var modelLoader:Loader3D;

var myBitmap:Bitmap
var textureLoader:Loader
//var material:ColorMaterial

function initView()
{
 view = new View3D();
 view.backgroundColor = 0x666666;
 //position and target the camera
 view.camera.lens = new PerspectiveLens()
 view.camera.position = new Vector3D(0,50,-80);
 view.camera.lookAt(new Vector3D());

var myBitmap:TextureMaterial;

If your using flash cs5 or what have you you still can use flex code, What you need to do is download flex SDK 4.6 or the latest and add the lib path to your document class smile

works for me!
