Re: [osg-users] Multi-Node?
How does Chromium stack up ? Its based on WireGl I believe and from what I've heard isn't the fastest API out there - If your forwarding calls every frame and rendering large databases in real-time wouldn't it be a pretty heavy load on your system?

Hi Paul, When you say Multiple Nodes what exactly do you mean... Do you simply mean a compute by Node, or graphics card or an osg::Node object in the scene graph... osgViewer does support multiple threaded, multiple displays on a single machine. It doesn't directly support a cluster of machines, one needs to implement this at the application level. Robert.

Thanks Robert - osgcluster seems a good starting point.

Does anyone know if OpenProducer has this support. Producer only supports multiple displays on a single machine, it has no cluster support. osgViewer that exist in 2.x replaces osgProducer/Producer and has the multi threaded muiltiple display capability that Producer has plus extra OSG centric high level viewer classes, threading models and support for distortion correction. osgVierwer like Producer doesn't have out of the box support cluster though. There are various ways to do clustering. The osgcluster example is a very very basic example that uses UDP packets to sync the view matrices and frames update. 3rd party solutions like Equalizer and VR Juggler has cluster support and integrate with the OSG. Lots of companies roll their own clustering solution too. Robert.
