3D tag cloud for Flex

Question

I'm trying to use this one class to create the tag cloud to flex.
1.I created a master document.
?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
   xmlns:s="library://ns.adobe.com/flex/spark"
   xmlns:mx="library://ns.adobe.com/flex/mx"
    creationComplete="init();" minWidth="955" minHeight="600" xmlns:local="*">
<fx:Script>
<![CDATA[
import mx.core.IVisualElement;
import mx.core.UIComponent;
public var inputWordr:String = "";
private function init():void {
c20.addElement(tirs as IVisualElement);
]]>
</fx:Script>
<fx:Declarations>
<local:MyComponent id="tirs" x="0" y="0" width="300" height="300"/>
</fx:Declarations>
<s:BorderContainer x="10" y="38" width="542" height="428" id="c20">
</s:BorderContainer>
</s:Application>
2. And created a class (MyComponent.as) based on code from the example and import all required swc.
package
import flash.display.BitmapData;
import flash.display.Sprite;
import flash.events.Event;
import flash.filters.BitmapFilterQuality;
import flash.filters.BlurFilter;
import flash.filters.GlowFilter;
import flash.text.TextField;
import mx.core.UIComponent;
import org.papervision3d.core.geom.Particles;
import org.papervision3d.core.geom.renderables.Particle;
import org.papervision3d.events.InteractiveScene3DEvent;
import org.papervision3d.materials.special.BitmapParticleMaterial;
import org.papervision3d.objects.DisplayObject3D;
import org.papervision3d.view.BasicView;
public class MyComponent extends Sprite
private var scale:Number = 5;
private var radius:Number = 350;
private var smoothing:Boolean = true;
private var minAlpha:Number = 0.3;
private var glow:GlowFilter;
private var tags:Array;
private var tag_num:uint;
private var bv:BasicView;
private var tagArray:Array;
private var tagContainer:DisplayObject3D;
public function MyComponent()
init ();
private function init ():void {
glow = new GlowFilter (0x003366, 1, 8, 8, 2, BitmapFilterQuality.LOW, true, false);
tags = ["free","news","Cookie","practice","JavaScript","toy","life","something","LocalConnection ","memo","MSN","funny", "ActionScript 3", "Food", "Book", "Photo", "favorite"];
tag_num = tags.length;
tagArray = [];
tagContainer = new DisplayObject3D ("tag_container");
tagContainer.x = -radius * 0.25;
tagContainer.y =  radius * 0.25;
bv = new BasicView (300, 300, true, true);
bv.viewport.interactive = true;
bv.scene.addChild (tagContainer);
bv.camera.z = -2 * radius;
bv.camera.zoom = 20;
bv.startRendering ();
addChild (bv);
buildTags ();
addEventListener (Event.ENTER_FRAME, enterFrameHandler);
private function buildTags ():void {
var i:uint;
for (i = 0; i < tag_num; i++) {
// 2D
var txt:TextField = new TextField ();
txt.text = tags[i];
txt.filters = [new BlurFilter(1.1, 1.1)];
var txtW:Number = txt.textWidth + 4;
var txtH:Number = txt.textHeight + 4;
var bitmap:BitmapData = new BitmapData (txtW, txtH, true, 0x01FFFFFF);
bitmap.draw (txt);
var phi:Number = Math.acos((2 * (i + 1) - 1) / tag_num - 1);
var theta:Number = Math.sqrt(tag_num * Math.PI) * phi;
// 3D
var material:BitmapParticleMaterial = new BitmapParticleMaterial (bitmap);
material.interactive = true;
material.smooth = smoothing;
var tag:Particle = new Particle (material, scale, 0, 0, 0);
var tagHolder:Particles = new Particles ("tag_");
tagHolder.addParticle (tag);
tagHolder.x = radius * Math.cos (theta) * Math.sin (phi);
tagHolder.y = radius * Math.sin (theta) * Math.sin (phi);
tagHolder.z = radius * Math.cos (phi);
tagHolder.useOwnContainer = true;
tagHolder.autoCalcScreenCoords = true;
tagHolder.addEventListener (InteractiveScene3DEvent.OBJECT_OVER, objectOverHandler);
tagHolder.addEventListener (InteractiveScene3DEvent.OBJECT_OUT, objectOutHandler);
//tagHolder.addEventListener (InteractiveScene3DEvent.OBJECT_PRESS, objectPressHandler);
tagContainer.addChild (tagHolder);
tagArray.push (tagHolder);
private function objectOverHandler (e:InteractiveScene3DEvent):void {
bv.viewport.buttonMode = true;
e.target.filters = [glow];
private function objectOutHandler (e:InteractiveScene3DEvent):void {
bv.viewport.buttonMode = false;
for (var j:uint = 0; j < tag_num; j++) {
tagArray [j].filters = [];
private function enterFrameHandler (e:Event):void {
tagContainer.rotationX += (mouseY - 300 * 0.5) * 0.01;
tagContainer.rotationY += (mouseX - 300 * 0.5) * 0.01;
for (var j:uint = 0; j < tag_num; j++) {
tagArray[j].alpha = minAlpha + (1 - minAlpha) * (1 - (tagArray[j].screen.z - radius) / (2 * radius));
3. Then I created a call of custom component, but nothing is displayed or causes errors. I tried to insert this component in different ways.
Check out where I made mistakes, please.
