SwingToTexture: How to update a part of an image (texture)?

Troubleshooting graphics

Hi!



I’ve written a SwingToTexture renderer with LWJGL. Now i want to port it to jme3… Swing only updates the “dirty regions” of a BufferedImage and i only want to update these regions for performance reasons, too. With LWJGL its pretty simple using the OpenGL command glTexSubImage2D. But i guess, its not a good idea to mix openGl commands and jme, is it ?



What i found is the Image.setData() method which calls “setUpdateNeeded” internally. But i guess that this method causes a full update of the whole texture !?



Please dont ask why i want to use Swing instead of Nifty. I just dont like Nifty …



I also had a look at the JMEDesktop class from JME2, which uses ImageGraphics to render the dirty regions. Actually i dont need this because i already have the image data but it must be uploaded to the texture…



Regards,



Chris

Hi Chris,

Were you able to do this? If so, how did you do it?

Thanks, Philip
