[JAVA3D] Texture Map

[JayT]

Hi,

I've been having a strange problem utilizing:

com.sun.j3d.utils.geometry.Box
com.sun.j3d.utils.image.TextureLoader
javax.media.j3d.OrientedShape3D

I'm trying to make a billboarded texture map image in the scene.
I utilize the Box object and have the TexureLoader load a texture map
onto it.

Then I obtain the proper Geometry object to generate and OrientedShape3D.
Unfortunately, unless I refresh the scene, I get a white square.

I use the runtime options:
java -Xmx160000000 -ms128000000 -Dj3d.3ddevice=hardware -Dj3d.sharedctx=false
