To obtain BufferedImage from Scene 3D

Question

Hi all!!! I want to obtain snapshots from Scene 3D to do a video with JMF (Java Media Framework). How I do it??
Regards!

// read the buffer to byteBuffer
            GL11.glReadBuffer(GL11.GL_FRONT);
            ByteBuffer pixels = ByteBuffer.allocateDirect(400*400*4);
            GL11.glReadPixels(0, 0, 400, 400, GL11.GL_RGB, GL11.GL_UNSIGNED_BYTE, pixels);
            ColorModel glColorModel = new ComponentColorModel(ColorSpace.getInstance(ColorSpace.CS_sRGB),
                                            new int[] {8,8,8,0},
                                            false,
                                            false,
                                            ComponentColorModel.OPAQUE,
                                            DataBuffer.TYPE_BYTE);
            int[] bitMasks = new int[] {8,8,8,0};
            int[] band = new int[3];
            // again, what is this?
            SinglePixelPackedSampleModel sampleModel = new SinglePixelPackedSampleModel(DataBuffer.TYPE_BYTE, 400, 400,bitMasks);
            // make array from byteBuffer to make a DataBufferByte from array...
            byte [] byteA=new byte[400*400*3];
            System.out.println(byteA.length);
            pixels.get(byteA);
            DataBuffer db = new DataBufferByte(byteA, 400*400*3, 0);
            //make my raster
            WritableRaster raster = Raster.createInterleavedRaster(db, 400, 400, 400*3, 3, band, null);
            // make my image
            BufferedImage image = new BufferedImage(glColorModel, raster, false, null);//new java.util.Hashtable());the above produces an image! yey! it is however grayscale, can anybody help?
