DESCRIPTION

19      callback  is invoked by OpenGLUT to refresh an overlay, if OpenGLUT
20     thinks that this is necessary.  Generally, very similar to glutDisplay‐
21     Func(), save that:
22
23      - The redisplay is triggered differently.
24      - OpenGLUT sets the layer for you.
25      - You do not need to have, and can deregister, this callback.
26
27     This callback is bound to  both  the  current window   and the  layer  .
28

BUGS

30     OpenGLUT does not implement layers at this time.
