Re: [osg-users] Problem with animations on VR platform.

David, In VR Juggler applications, we typically pull a timestamp value from a tracker device to make sure that all cluster nodes have the same value at each frame. For OSG animations, I don't know the exact solution, but it sounds like Robert has given you some destinations for the time

Re: [osg-users] Draw threads serialized by default?

Robert, The post of yours that Paul linked to sounds very similar to something we saw with VR Juggler OSG a while back: terrible performance with OSG apps that had parallel draw threads. In our case, VR Juggler manages threading, but the same may apply to OSG with osgViewer. For us, it

I'm interested in getting the community's input on the best way to export from Maya to an OSG-readable format. I'm looking for something that will support scene structure, textures, and potentially shaders. We tried FLT export from Maya, but the textures didn't come into OSG. Has anyone come

I have some code that creates OSG boxes and applies materials to the geodes containing those boxes. It creates a flat scene graph (for now) with an osg::Group root node and an osg::MatrixTransform attached to the root node above each geode. I've noticed a huge frame rate reduction when I

Re: [osg-users] OSG and vrJuggler

VR Juggler has an osg::App class that you can derive from to use OSG with it. There is also an osgNav example application that you should be able to run use. If you get the latest VRJ source tree, there is also a new osg::AppViewer class, which is based on osgViewer instead of SceneView.

This is probably more of a topic for the VR Juggler mailing list, but you need to: 1. Make a jconf file for your cluster (which it sounds like you already have from VE Suite), and 2. Run your application on each node of the cluster. I think there are a few different mechanisms for starting up
