Hi Kevin, thank you for your fast reply, but it still not work
>Looking at the code for model2sprite (http://model2sprite.dev.java.net) >three things might be worth trying: > >1) Make sure rendering your scene to a normal canvas actually shows >something. This works , I use the HelloUniverse Demo with a cube3d and a normal canvas shows the Image without problems. >2) Try using c.getOffscreenBuffer().getImage() after the rendering instead >of relying on you're original image. This was not successful, but this the same like using the reference of the BufferedImage I used to create the Buffer. >3) Try causing the scene to render a few times >(c.renderOffScreenBuffer(),c.waitForOffScreenRendering()) before using the >image, since some behaviors need a few frames to get going. There was Nothing after 100 renderings Shit !!!!!!!! >I'm not sure what you're doing with the View.addCanvas3D() thing, its not >quite the same as how I did it.
