Away3D Forum Having trouble wrapping a Sphere in a Texture/Bitmap

Hi All,

I’m having trouble loading a texture on a primitive Sphere.

Can anyone help?

I’m using Away3D.4.Beta and FlashDevelop.

This is a class that creates a sphere and adds it to Scene3D (lescene) and adds an EventListener to View3D (cam). Both View3D(cam) and Scene(lescene) are passed to it.

The code works fine (great actually) without the texture, just the color red, but when I attempt to load the texture, I just get a black screen.

The code is below. What am I doing wrong?

package  
{
 import away3d.cameras.Camera3D;
 import away3d.containers.Scene3D;
 import away3d.containers.View3D;
 import away3d.entities.Mesh;
 import away3d.materials.ColorMaterial;

 import flash.display.Loader;
 import flash.display.MovieClip;
 import flash.geom.Vector3D;
 import flash.net.URLRequest;
 import flash.system.Capabilities;
 import flash.utils.Timer;
 import mx.controls.videoClasses.INCManager;
 import away3d.cameras.*;
 import away3d.containers.*;

 import flash.filters.*;

 /**

 public class spherey extends Sprite
 {
  //Objects
  private var mesh:Mesh;
  private var sphereGeometry:SphereGeometry;
  private var sphereMaterial:TextureMaterial;
  
  //Embeds
  [Embed(source = "../../3d_objects/Textures/globeprototype.jpg")]
  private var map:Class;
  
  
  public function spherey(cam,lescene) 
  {
   init(cam,lescene);
  }
  
  private function init(cam,lescene):void
  {
   startEngine(cam,lescene );
  }
  
  private function startEngine(cam,lescene):void
  {
   sphereGeometry = new SphereGeometry(500,100,100);
   sphereMaterial = new TextureMaterial(new BitmapTexture((new map()).bitmapData));
   mesh = new Mesh(new SphereGeometry(500,100,100), sphereMaterial);
   lescene.addChild(mesh);
   cam.addEventListener(Event.ENTER_FRAME, onEnterFrame);
   }
   private function onEnterFrame(event:Event):void
   {
   mesh.rotationY++;
   event.target.render();
   }
  
 }

} 

Also, the location of the embed is correct, the code works when the sphere is a color instead of a texture.

private function startEngine(cam,lescene):void
{
   sphereGeometry = new SphereGeometry(500,100,100);
   sphereMaterial = new ColorMaterial( 0xff0000 );
   mesh = new Mesh(sphereGeometry, sphereMaterial);
   lescene.addChild(mesh);
   cam.addEventListener(Event.ENTER_FRAME, onEnterFrame);
 }

For so far I see, it should work. Try with some non-embed bitmapData?

When I use the texture script, all I get is a black screen. Nothing shows, at all. When I change back to the color, the full script runs. I can try without the embed and see how that goes.

How would I do it without an Embed? (Still trying to learn the basics since the update to Away3D.4.Beta)

Hmm I think that you can access the bitmapData of a Shape (see AS3 Shape class) .

try:

var bmp : Bitmap = new map() as Bitmap;
sphereMaterial = new TextureMaterial(new BitmapTexture(bmp.bitmapData));

Thanks Vice, but all I get is a black screen.

A completely black screen.. nothing shows.

is your texture a square file with multiplications from 2?

so for example 256x256, 1024*1024 or 2048*2048?

No, the texture isnt. Should I make it so? I could do that.

Ill try it.

I didn’t test the code but that should make it:

// creating the mesh
var geometry:SphereGeometry = new SphereGeometry (100);
var sphere:Mesh = new Mesh(geometry);
scene.addChild(sphere);

// loading texture
var url:String = 'image.jpg';
var Ldr:Loader = new Loader();
Ldr.load(new URLRequest(url));
Ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onComplete(e:Event):void
{
     var bitmap:Bitmap = Bitmap(Ldr.content);
     var bitmapData:BitmapData = bitmap.bitmapData;
     var texture:BitmapTexture = new BitmapTexture(bitmapData);
     var material:TextureMaterial = new TextureMaterial();
     material.texture = texture;
     sphere.material = material;
}
