single GLContext (not shared context) for multiple GLWindows?
Hi All. Thanks for all the great work on JOGL :-)
I am trying to take advantage of Newt and GLWindow for a Swing and JOGL based application, and am looking for the smartest way to share lots of buffered data, textures, compute shader data, and VAOs for rendering different parts of a large GPU-computed data set. While a single GLWindow and multiple viewports works fine, it all gets painful trying to layout a Swing UI around the viewports.
So I've tried to use a set of GLWindows and a single GLContext.
Has anyone successfully implemented a GLContext singleton and use in multiple GLWindows?
GLWindow glWindow.setContext(...) called before the glWindow is visible leads to "GLWindow.LifecycleHook.setVisiblePost: ... - Null drawable, but valid context - NEWT-GLWindow".
After visibility, it seems to only lead to "...being incorrectly used with a different GLContext than that which created it" or " makeCurrent() failed with new drawable X11OnscreenGLXDrawable..."
I can try and strip things down to a minimal test case, but before I go too far down that road, I'd like to know I'm not being silly, or redundant.
