Windowless offscreen rendering

Dear all,

First of all I would like to thank you for all your efforts to make JOGL a wonderful OpenGL Java binding and I like it a lot.
I would love to see more user guide or documentation about the internal architecture.
For example, I am currently doing offscreen rendering using pbuffer but it seems I still need to attach a canvas to the window system. Is there anyway to do it without windowing system (i.e. no Frame just console command line?)

I learn from Ken Russell that I can make a zero size frame without decoration but still I wonder if there’s a way to do offscreen rendering without a window system at all.

Thanks
Aaron

I looked into that for windows but the amount of native code required was huge. You can give it a go yourself of course. You just have to find a appropriate display device and create a device context for it, and then plug that into the pbuffer creation function.
