I saw that you have to call this:
glXMakeCurrent(glXGetCurrentDisplay(), glXGetCurrentDrawable(), ?? )
if you want to start rendering from a new thread. I don’t understand the third parameter.
Any clues? (I saw this: http://www.x.org/archive/X11R6.8.2/doc/glXCopyContext.3.html and still dont get it).
Thanks,
Dave
