Hi Alessandro and Ben, Thanks for you all.
I am sorry I am not clear of my problem. With the sample code, I can add 2 or more images/icons to one cube face, but this is static and the images are overlapped. As you know, I can manully manage the location, so the multiple images will not overlap, this is not what I want. For example, one time, I have 3 images which order is image01, image02 then image03 order, I will show all this three images as the order 01,02,03. Next time, the images order is different, so what should be shown is image10, image02, image08, then image03 then image18 etc, So the images is different and order is different too. If I could manage the multiple images to be one image, then paste to 3D cube, will resolve this problem. Or if I can put every image to the specified location of a cube front face, this will resolve the problem too. Ben, you mean the Java2D can combine the multiple images to one image? Could you please give a little more details about this issue??
