Hi

Started from fresh and now I am able to get around 30 ms with PBO.Thx lot your support.
I think while wrapping the BuffereData I was doing wrong .

Now I want to zoom this image
I used following API but image didn't zoomed any other API I have to look in ...
       // Zoom
      gl.glLoadIdentity();
      gl.glTranslatef(-15.0f,-15.0f,0.0f);
Pls can you help me out

Hi Mabraham /Ken
 I didn't get any reply for below post pls can anyone reply .

Hi Mabraham /Ken
I upgraded my driver to NVIDIA 81.78.But still i performance are in 3 digit .

Here the Linux Machine Details and new readings on 81.78

Pls Can you suggest what else i can do to get good peformance .

One more thing is On my LINUX machine  gl.isExtensionAvailable( "GL_ARB_pixel_buffer_object" )     false
And gl.isExtensionAvailable( "GL_EXT_pixel_buffer_object" ) true
 Is this makes any difference in performance

Or only option left move to new GPU card.
pls let me know .

Thanks

Hi
Planing to buy following card on Linux .

Quadro FX 4500 Memory Size
Memory Interface
Graphics Memory Bandwidth
Graphics Bus 512MB
256-bit
33.6GB/sec.
PCI Express

Pls let me know if some one already using this card  ,which will enable to get good performance for PBO .

When run it on my Linux Machine it show following out put ...

These are in msec right?
Just want to know any thing extra I have to do so that I will get 25 ms second to render and display the 2048 x 2048 Buffered image?

Thx Lot ! It is working fine .

Attached is the modified GLEventHandler.txt file .
Pls can you tell me what i am doing wrong .
grep for    images=genImages(5,2022) in attached file .
Also pls can you send me the screen capture of your display .

Thx

Attached is the OpenGL pattern

Thx Lot. But i am facing one problem

In Java 2d I created following BufferedImage ...
BufferedImage[] bi = BufferedImage.TYPE_4BYTE_ABGR;
DataBufferByte dbb = (DataBufferByte ) bi.getRaster().getDataBuffer();
byte[] data         = dbb.getData();
// TYPE_4BYTE_ABGR
byte max = (byte) 0xff;
        for (int i = 0; i < w; i++)
            for (int j = 0; j < h; j++)
                if (j % 40 < 20)
                {
                    int basePixel = (i * w + j) * 4;
                    d[basePixel]     = (byte)0xff;
                    d[basePixel + 1] = max;
                    d[basePixel + 2] = max;
                    d[basePixel + 2] =max;
                }
It shows the vertical bars with alternate one black .Attached Doc.

Same thing I added in your GLEventHandler.java program
byte max = (byte) 0xff;
        for (int i = 0; i < w; i++)
            for (int j = 0; j < h; j++)
                if (j % 40 < 20)
                {
                    int basePixel = (i * w + j) * 4;
//OpenGL                   
                d[basePixel]      = max ;
                d[basePixel + 1] = max;
                d[basePixel + 2] = max;
                d[basePixel + 2] =(byte)0xff;

                }

   It shows some bad pattern image(it is not same as in java) , Can u suggest what’s  wrong.
I am excepting the same pattern as in JAVA 2D.

Ok Thx Lot .
I am looking for some main Java progarm which will use GLEventHandler.java and show the image do you have any main program ?pls can you send me the link or code .

1) You said "Unless you really need to go OpenGL, you can nowadays get equally fast image updates using java2d..."

Pls can you tell me how to achive this using only java2d no openGL ?

2) I am new to this jogl .How to give input bufferedImage to your program GLEventHandler.java ?Do you have any main program using GLEventHandler.java which will load the given BufferedImag

I am looking for some sample program which can render and dispaly   "2k x 2k  2D image "  in less then 25 msec .
If any one has idea let me know

I am looking for some sample program which can draw  "2k x 2k  2D image "  in less then 25 msec .
If any one has idea let me know

 Is their any sample code for  "To draw  images using a texture-mapped quadrilateral then on a GLCanvas using OpenGL which will give very good pefromance ". Pls can send me the demo program it will be great help .
Thx Lot

Hi Ken Russell
   Thx Lot for the info.
   Is their any sample code for  "draw your images using a texture-mapped quadrilateral then on a GLCanvas using OpenGL should be very fast " .  Pls can send me the demo program it will be great help .

Thx Lot

 I am very new to this JOGL .
    I am runing on linux os and JDK1.4
    in  JGears.java demo ,
    if (javaImage != null) {
        g.drawImage(javaImage, sp, getHeight() - javaImage.getHeight() - sp, null);

      if (openglImage != null) {
                 g.drawImage(openglImage, sp, getHeight() - openglImage.getHeight() - sp, null);
      }

1) This is normal java 2D software rendering .Why two javaImage and openglImage required when both are draw using drawImage?.
2) How GLJPanel will enable openGL image rendering ?I looked at paintComponent but didn't get much information.
3) I commented the paintComponent  of GLJPanel but still able to draw the images ?Just wanted to know how
    openGL accelartion is performed ?
4) Is there any demo which will comapre normal Java 2D image draw and open GL hardware accelarted image draw  performance .
