Hi everyone.

im still learning about this framework, and while i was doing some test, i got into a problem

i have an xml file, wich i load into my aplication, then i get an array, with the address of some images. (img/file1.jpg,img/file2.jpg.. etc)

once the images are loaded (with event.complete listener), i wanna create a plane and add this image to this plane.. but nothing i do seams to work out.

my code is:

var my_loader:Loader = new Loader();
my_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,createPlane)
var fileRequest:URLRequest = new URLRequest(aDirArchivo[n]);//addres of imagen
my_loader.load(fileRequest);
}

//then in  createplane function

public function createPlane(e:Event):void
{
var oPlane:PlaneGeometry = new PlaneGeometry(256,256,1,1,false);
var omPlane:BitmapTexture;
var tPlane:TextureMaterial;

// i cant have the clasicc
//omPlane = new BitmapTexture(new class().bitmapData);
//so this line, i dont know how it so create this objec material..

omPlane = new BitmapTexture( ???.bitmapData);

//:( 

any ideas??

thx a lot

Here’s one way to handle it.

var nMaterial:TextureMaterial = new TextureMaterial( new BitmapTexture( Bitmap( my_loader.content ).bitmapData ) );

var oPlane:PlaneGeometry = new PlaneGeometry( 256, 256, 1, 1, false );
var oPlaneMesh:Mesh = new Mesh( oPlane, nMaterial ); 

You can also do this to get the BitmapData, which is good if you need to resize or modify the incoming image.

var nBMP_D:BitmapData = new BitmapData( 256, 256, false, 0x00000000 );

var nSprt:Sprite = new Sprite();
nSprt.addChild( my_loader );
// resize, enhance, whatever +++
nBMP_D.draw( nSprt );

var nMaterial:TextureMaterial = new TextureMaterial( new BitmapTexture( nBMP_D ) ); 

Anyways, hopefully that helps and hopefully I didn’t just have a brain-fart and put up gibberish, because I forgot something…

You can also use the inbuilt AssetLibrary to load your textures,
which is probably good practise. Here is an example:

private var textureURL : String = 'texture.png';
private var textureMat : TextureMaterial = new TextureMaterial();

public function loadMaps() : void {

 var loadToken : AssetLoaderToken = AssetLibrary.load( new URLRequest( textureURL ) );
 loadToken.addEventListener(AssetEvent.ASSET_COMPLETE, onAssetLoadComplete );

}

private function onAssetLoadComplete(event : AssetEvent) : void {

 var bmd : BitmapTexture

 switch ( event.asset.name ) {
       
  case textureURL:
    
   bmd = AssetLibrary.getAsset( event.asset.name ) as BitmapTexture;
   textureMat.texture = bmd;
       
   break;

 }

}

after loading bitmap image vb, you can get the bitmapdata, and then you can process images:reszie scale and crop by using the codes above.

as i can see, this is vb.net method to load image from file, i am a C# expert, so can you provide some c# sample codes for loading image from file.
thanks.
