[JAVA3D] Textures and transparency

[Paula Keohan]

Hi all,

I've created an Appearance object from a Texture2D object. I've set the
transparency attributes of the appearance also. But, when I change the alpha
value, it doesn't have any effect on the appearance. Anyone got any ideas
why the transparency doesn't change? Is it just not possible with textures
created from images? I've included code below.

Thanks,
Paula.


Appearance textureAppearance = new Appearance();
  TransparencyAttributes transparency = new TransparencyAttributes(
        TransparencyAttributes.NICEST, .85f);

  PolygonAttributes polyAttrib = new PolygonAttributes();
  polyAttrib.setCullFace(PolygonAttributes.CULL_BACK);
  textureAppearance.setPolygonAttributes(polyAttrib);

  TexCoordGeneration tcg = new
TexCoordGeneration(TexCoordGeneration.OBJECT_LINEAR,
       TexCoordGeneration.TEXTURE_COORDINATE_2);
  textureAppearance.setTexCoordGeneration(tcg);

  String filename = texturefilepath.getAbsolutePath() + File.separatorChar +
texturename;

  TextureLoader loader = new TextureLoader(filename, this);
  ImageComponent2D image = loader.getScaledImage(1024, 1024);

  Texture2D texture = new Texture2D(Texture.BASE_LEVEL, Texture.RGBA,
image.getWidth(),
              image.getHeight());
  texture.setImage(0, image);
  texture.setEnable(true);

  textureAppearance.setTexture(texture);
  textureAppearance.setTransparencyAttributes(transparency);
