Scratching my head over this one…
I need to dynamically load an image, and I’m adding that as a child to a movieClip which is the texture for a BitmapMaterial.
var fLQmc:MovieClip = new MovieClip;
var frontCoverloader:Loader = new Loader()
var frontCoverRequest:URLRequest = new URLRequest("http://videoemporium.co.uk/movie_title_covers/covers/LQ/fLQ/4700/4759fLQ.jpg");
frontCoverloader.load(frontCoverRequest)
frontCoverloader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadFront);
function loadFront(e:Event):void
{
//trace ("front Cover Loaded")
//addChild (frontCoverloader)
//var mat:Matrix = new Matrix (256 / frontCoverloader.height, 0, 0, 256 / frontCoverloader.height, 0, 0);
//fLQmc.BitmapData = new BitmapData(256, 256)
//fLQmc.BitmapData.draw (mat,frontCoverloader)
fLQmc.addChild(frontCoverloader);
addChild(fLQmc);
materials.updateTexture;
}
and then later:
var materials: BitmapMaterial = new BitmapMaterial (fLQmc.bitmapData)
// Create a cube with DVD dimensions
var p:Cube = new Cube( materials, DVDw, DVDh, DVDd);
but the cubes are all showing up white?

Hopefully you should be getting an error, as a MovieClip doesn’t have a bitmapData, only a Bitmap does.
You need to create a BitmapData, use the draw command to get a graphical representation of the movieClip, then use the bitmapData for your material.
var bmd:BitmapData = new flash.display.BitmapData(flQmc.width, flQmc.height, false, 0x00);
bmd.draw(flQmc);
var materials: BitmapMaterial = new BitmapMaterial (bmd);
Good Luck!

Aha, yep that seems to be working now… Kind of… I now need to get that matrix resize working..
Wasn’t giving me an error, just a white texture..
Now, oddly, it seems like the texture is offset? Up on the top left is the moveclip added to the stage, and on the lower right DVD case you can see how that translates to the texture…

Use a CubeMap, otherwise Away3D will spread the bitmap over all sides, instead of full map on each side.

Yeah, I was thinking that, and add the bitmap data at the relevant place?
3 x 2 grid correct?

To be honest, last time I looked I couldn’t quite work out how it was mapping to a simple Box, but it wasn’t a 3x2 as I’d guessed.
My advice, use the cubeMap. Then you can add different graphics to sides/back etc. If you want the same on all sides, just use then same BitmapData for each part of the CubeMap.

Yeah, I couldn’t figure it out either, I’ve been waiting for someone to make it all nice and easy for me in that respect, and with the power of 2 texture dimensions thing too…
Anywyas, so i tried:
var caseMaterials: CubeMap = new CubeMap (fLQBMD, fLQBMD,
fLQBMD, fLQBMD,
fLQBMD, fLQBMD);
p.material = caseMaterials;
gives me the error:
Error: Implicit coercion of a value of type away3d.materials.utils:CubeMap to an unrelated type away3d.materials:MaterialBase.
I’ve only seen the cubemap used with the skybox primitive, so not sure how to apply it to a cube…

This is not exactly an answer to your Bitmap question, but more about how to apply an image to a cube, if you’re still looking. I’ve had an issue about that too, so I wrote a blog post to share the solution I found: http://jansensan.net/apply-a-texture-on-a-cube-in-away3d-4-0
I hope that helps!

sorry for not being able to provide exact answer. i am happy to show you how to load image from file and how to dynamatically load image from web. if this can helps a little bit, i will be glad.
