in reply to OpenGL and AnyEvent

From a quick googling, it seems that at least some GLUT implementations, freeglut and openglut implement glutMainLoopEvent(), which is supposed to be called periodically from your other mainloop.

A second alternative would be to detach OpenGL processing from the rest of your program by using a separate thread to handle OpenGL. But then you need to make sure that all OpenGL-related resources get allocated from that thread. At least, I remember some stories of debugging two threads going tag-team on OpenGL handles in the early days of consumer OpenGL.

    Thank you, Corion!

    I've found that the main trick is to call glutPostRedisplay too, e.g. instead of glutMainLoop 

    my $refresh_world = sub {
    glutMainLoopEvent;
    glutPostRedisplay;
};
my $t; $t = AE::timer 0, 0.01, sub {
    $refresh_world->();
};
$refresh_world->();
AE::cv->recv;
