headless rendering

[renanse]

Hi folks,

I'm working again on implementing headless rendering support in jME for a Swing-jME integration.  Non-Headless works great already except that you have the render window sitting there behind your Swing window and it just looks bad.  Back in .90 LWJGL I started working on headless mode using pbuffer (similar to how GL4Java integrated OpenGL and Swing) but ran into the issue of not being able to create a pbuffer without a Display.   I was told this was fixed in .92 but when I try to do something like this:

headlessDisplay = new Pbuffer(width, height, format, texture);

I get an exception like this:

org.lwjgl.LWJGLException: Could not create Pbuffer.
   at org.lwjgl.opengl.Pbuffer.nCreate(Native Method)
   at org.lwjgl.opengl.Pbuffer.createPbuffer(Unknown Source)
   at org.lwjgl.opengl.Pbuffer.<init>(Unknown Source)
   at com.jme.system.lwjgl.LWJGLDisplaySystem.initHeadlessDisplay(LWJGLDisplaySystem.java:475)
   at com.jme.system.lwjgl.LWJGLDisplaySystem.createHeadlessWindow(LWJGLDisplaySystem.java:164)

   at com.jme.app.BaseGame.start(BaseGame.java:59)
   at com.mpgrealm.dirt.test.SwingTest2.main(SwingTest2.java:67)

Any ideas?  Looking at the native code it seems like a problem maybe with findPixelFormat since all the others throw an exception.

I don't think you'll be able to make LWJGL integration in Swing... For the moment, there's only a SWT binding around the web...
How, also, to instead of using PBuffer, you should look into the Display.setContext() method, it could help you

Actually, it works just dandy  I'm looking for help with standalone Pbuffers so no worries about switching of context.  but thanks.

Ok, my problem was I was passing in a RenderTexture object...  passing in null for that arg in the Pbuffer contructor ended up solving that problem.  So now I have a Swing window showing off some animated lwjgl created content via jME.  Cleaning and optimizing ahead, but I'm excited at the results.
