Fixed the problem.
With the j3d opengl on my 3d card (radeon 7500 mobility) the textures
are managed using 16 color bits. But using the j3d directx (1.3.1) the
texture are showned using 24 bit.

answer:
1) yes. But, as far as I know,  jpg is a 24 color bit image format.
Check if your vcard is also set to 32/24 color bits. My vcard also
shows ugly textures at 16bits.

2)yes.  You can set a colored geometry as background.  Try a cube,  or
a cylinder, and set a color for each vertex. Turns normals and
material lighting off.

    I've tried to make a gradient background for my 3d scene: i've
    created a
    simple jpg from cyan to white, and i've added to the scene with:

    TextureLoader loader = new
    TextureLoader(Param.installDir+"\\images\\3dbg.jpg", c);

    ImageComponent2D image = loader.getScaledImage(dim.width,dim.height);

    gui.bgNode.setImage(image);

    It works, but seems that the image was converted in 16bpp, so the
    gradient are no smooth but very ugly.

    1) Can i use a 32bpp (or 24bpp) image like background?
    2) There is another way to make a gradient background without images?
