Has anyone done any work sharing OpenGL contexts in Clojure? I was wondering the best way to create a GLCanvas if I want all of them to share the same context.
Right now it seems calling (.getContext (new GLCanvas)) returns nil, which may be a JOGL thing, but I was hoping to create one canvas with the argument-less GLCanvas constructor and once one is made use its context to create the other ones that take a context in their constructor. The JOGL user's guide isn't too detailed about how this works. http://download.java.net/media/jogl/builds/archive/jsr-231-1.1.0/jogl-1.1.0-windows-i586/Userguide.html I'm curious in general how an OpenGL program should properly be written when dealing with multiple windows. If I were to make a change to the data in memory, my instincts would be to set it as "dirty" and have the first GLCanvas rebuild the OpenGL stuff, set the data as clean, and have the other GLCanvases use the updated OpenGL stuff (VBOs, display lists, textures, etc.). I figure since it's all single threaded, I wouldn't need any locks on a process like that in Java, correct? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
