I try to make a website where you can navigate by travelling through a galaxy, but to make things a bit more complicated i try to put a 3d view of it.

After long search i came to the conclusion to use papervision3d.

It is this picture of our Milkyway  
[http://ddg.trackers-world.net/gal\_1280.html](http://ddg.trackers-world.net/gal_1280.html)

from a different viewing angle  
[http://ddg.trackers-world.net/galview\_side.html](http://ddg.trackers-world.net/galview_side.html)

but as you can see, or not see, my picture is not displayed, only the BitmapFileMaterial without the \*.jpg, which i put into the same directory as the \*.swf, like on my harddrive where i can see it.

Also it seems that the Picture is not rendered correctly, and i found that there is precision texture mapping to view it correctly. but i cant get it to work.

```auto

package
{
    import flash.display.Sprite;
    import flash.events.Event;
    
    import org.papervision3d.cameras.Camera3D;
    import org.papervision3d.materials.BitmapFileMaterial;
    import org.papervision3d.objects.Plane;
    import org.papervision3d.scenes.MovieScene3D;

    [SWF(width='800',height='800',backgroundColor='0x000000',frameRate='30')]
    
    public class ExampleBitmapFileMaterial extends Sprite
    {
        private var container :Sprite;
        private var scene :MovieScene3D;
        private var camera :Camera3D;
        private var plane :Plane;
            
        public function ExampleBitmapFileMaterial()
        {
            container = new Sprite;
            container.x = 500;
            container.y = 300;
            addChild( container );
                                    
            scene = new MovieScene3D( container );
            
            camera = new Camera3D();
            camera.y = -100;
            camera.z = -100;
            camera.zoom = 7;
                        
            // "sig05-010a_1024.jpg" is the picture of the Galaxy
            var material:BitmapFileMaterial = new BitmapFileMaterial("sig05-010a_1024.jpg"); 
            material.doubleSided = true;
            material.smooth = true;
        
            plane = new Plane( material, 256, 256, 2, 2);

            scene.addChild( plane );
        
            stage.addEventListener( Event.ENTER_FRAME, onEnterFrame );

        }

        private function onEnterFrame( event: Event ): void
        {
            // render scene
            scene.renderCamera( camera );

        }
        
    }
    
}

```

also, how do i let the picture rotate around its center?
