Thanks for the reply,
well, I still got no success.. I found that just changing from ClusterWindow
to MultiDisplayWindow makes all to work (since Im using only one viewport
and one server (hservers x wservers = 1 x 1), multidisplaywindow works just
like the clusterwindow should. But using the clusterwindow yields a black
screen at servers. The connection is performed just like it is with
MultiDisplayWindow (log level at server shows connection establishment). It
seems to be something naive I'm missing..
Im using two windows, one passive to render locally, and the other one to
perform remote cluster rendering... I wonder if there's something I should
do to render the cluster window (anything that is performed automatically by
multidisplaywindow render() but not by clusterwindow?), something like
frameInit() or anything like that. Im sending my code below:
... build scene root and stuff...
_clusterWindow->setSize( serversWidth, serversHeight );
OSG::ViewportUnrecPtr vp = OSG::Viewport::create();
vp->setRoot( _currentState.getRoot() );
vp->setCamera( _currentState.getCamera() );
vp->setBackground( _currentState.getBackground() );
vp->setTravMask( 1 );
_clusterWindow->insertPort( 0, vp.get() );
OSG::Thread::getCurrentChangeList()->commitChangesAndClear();
OSG::Thread::getCurrentChangeList()->fillFromCurrentState(
Application::getFirstFCId() );
_clusterWindow->init();
_clusterWindow->render( _renderAction );
OSG::Thread::getCurrentChangeList()->clear();
_clusterEnabled = true;
(I start the app using a single passive window, and then the cluster is
enable on the fly, that's why I need fillFromCurrentState()).
Using multidisplaywindow makes all to work, but I can't get clusterwindow
alone to work..
Any hints? :/
Thanks!
