Slightly off the topic question I'm afraid...
But, I've always been led to believe that Performer 1.2 did not let processes
forked off the application process modify the scenegraph... So either this
is not true or "a separate rebuilding process [that] let the visuals continue
to run typically at 60Hz. " did not directly modify the scenegraph and
achieved this some other way. Maybe I've missed something here.
Thanx.
