[away3d] How to do more clarity BitmapMaterial

[metSyS]

Can't understand how to do BitmapMaterial more clarity. I've tried
everything I knew, I don't want to use movie material. Here's my
code :

package {
        import away3d.cameras.HoverCamera3D;
        import away3d.containers.ObjectContainer3D;
        import away3d.containers.Scene3D;
        import away3d.containers.View3D;
        import away3d.core.base.Object3D;
        import away3d.core.render.Renderer;
        import away3d.events.MouseEvent3D;
        import away3d.materials.BitmapMaterial;
        import away3d.materials.MovieMaterial;
        import away3d.primitives.Plane;
        import away3d.primitives.Trident;

        import caurina.transitions.Tweener;

        import flash.display.BitmapData;
        import flash.display.Sprite;
        import flash.events.Event;
        import flash.text.TextField;

        [SWF(width="1024", height="768", frameRate="30",
backgroundColor="0xAAAAAA", quality="high")]
        public class Away3D extends Sprite
        {
